Python Libraries – Python Standard Library & List of Important Libraries 2. What is the Python Libraries? We know that a module is a file with some Python code, and a package is a directory for sub packages and modules. But the line between a package and a Python library is quite blurred.

A Python library is a reusable chunk of code that you may want to include in your programs/ projects. Compared to languages like C++ or C, a Python libraries do not pertain to any specific context in Python.

Here, a ‘library’ loosely describes a collection of core modules. Essentially, then, a library is a collection of modules. A package is a library that can be installed using a package manager like rubygems or npm. Learn: 3. Python Standard Library The Python Standard Library is a collection of exact syntax, token, and semantics of Python. It comes bundled with core Python distribution. We mentioned this when we began with an introduction.

It is written in C, and handles functionality like I/O and other core modules. All this functionality together makes Python the language it is.

More than 200 core modules sit at the heart of the standard library. This library ships with Python. But in addition to this library, you can also access a growing collection of several thousand components from the Python Package Index (PyPI). We mentioned it in the previous blog. Learn: 4. Important Python Libraries Next, we will see twenty Python libraries list that will take you places in your journey with Python. These are also the Python libraries for Data Science.

a. Matplotlib Matplotlib helps with data analyzing, and is a numerical plotting library. We talked about it in . Python Libraries Tutorial – BeautifulSoup g. Pyglet Pyglet is an excellent choice for an object-oriented programming interface in developing games. In fact, it also finds use in developing other visually-rich applications for Mac OS X, Windows, and Linux. In the 90s, when people were bored, they resorted to playing Minecraft on their computers.

Pyglet is the engine behind Minecraft. Python SymPy Library s. Fabric Along with being a library, Fabric is a command-line tool for streamlining the use of SSH for application deployment or systems administration tasks. With it, you can execute local or remote shell commands, upload/download files, and even prompt running user for input, or abort execution. Python PyGTK Library Learn: So, this was all about Python Libraries Tutorial. Hope you like our explanation, 5. Conclusion Now you know which libraries to go for if you choose to extend a career in Python.

Many of these help us with data-science as well. Or if you wish to go out of your way, create your own library, and get it published with the PyPI; help the community grow. Furthermore, if you have any query, please share with us!

If you are a system administrator, it is likely that you have encountered Perl, Bash or some other scripting language. You may have even used one or more yourself.

Scripting languages are often used to do repetitive, tedious work at a rate and with an accuracy that far surpass what you could accomplish without them.

All languages are tools. They are simply a means to get work done. They have value only insofar as they help you get your job done better. We believe that Python is a valuable tool, specifically because it enables you to get your work done efficiently. The first reason that we think that Python is excellent is that it is easy to learn. If a language can’t help you become productive pretty quickly, the lure of that language is severely diminished.

Also Read: Here we’ve listed out 7 best python libraries which you can use for Data Validation:- 1. Cerberus – A lightweight and extensible data validation library. Cerberus is a lightweight and extensible data validation library for Python. Cerberus provides type checking and other base functionality out of the box and is designed to be non-blocking and easily extensible, allowing for custom validation.

It has no dependencies and is thoroughly tested under Python 2.6, Python 2.7, Python 3.3, Python 3.4, Python 3.5, Python 3.6, PyPy and PyPy3. To install Cerberus, use the following command: Command: pip install cerberus After complete installation, just type “ python setup.py test” • View on Github – • Official Link – • Documentation Link – • Latest Version – v1.1 Basically there are two versions are available: • Stable Version • Development Version Basic Syntax: >>> schema = {‘name’: {‘type’: ‘string’}} >>> v = Validator(schema) Live Example: >> schema = {‘name’: {‘type’: ‘string’}, ‘age’: {‘type’: ‘integer’, ‘min’: 10}} >>> document = {‘name’: ‘Little Joe’, ‘age’: 5} >>> v.validate(document, schema) False >>> v.errors {‘age’: [‘min value is 10’]} 2.

Colander – Validating and deserializing data obtained via XML, JSON, an HTML form post. Colander is useful as a system for validating and deserializing data obtained via XML, JSON, an HTML form post or any other equally simple data serialization. It is tested on Python 2.7, 3.3, 3.4, 3.5, and 3.6, and PyPy.

Colander can be used to: • View on Github – • Official Link – • Latest Version – v1.4 An extensible package which can be used to: • deserialize and validate a data structure composed of strings, mappings, and lists. • serialize an arbitrary data structure to a data structure composed of strings, mappings, and lists.

With Colander.Email() function – def emails_validator(node, kw): new_emails = [e for e in kw if isinstance(e, basestring)] validator = colander.Email() for email in new_emails: validator(node, email) 3. Jsonschema – An implementation of JSON Schema for Python. Jsonschema is an implementation of JSON Schema for Python (supporting 2.7+ including Python 3). • View on Github – • Official Link – • Latest Version – v2.6.0 It can also be used from console: Command: jsonschema -i sample.json sample.schema Features – • Full support for Draft 3 and Draft 4 of the schema.

• Lazy validation that can iteratively report all validation errors. • Small and extensible • Programmatic querying of which properties or items failed validation. 4. Schema – A library for validating Python data structures. Schema is a library for validating Python data structures, such as those obtained from config-files, forms, external services or command-line parsing, converted from JSON/YAML (or something else) to Python data-types. • View on Github – If data is valid, Schema.validate will return the validated data (optionally converted with Use calls, see below).

If data is invalid, Schema will raise SchemaError exception. Installation of Schema is very easy: Command: pip install schema Alternatively, you can just drop file into your project – it is self-contained. Schema is perfectly tested with Python 2.6, 2.7, 3.2, 3.3, 3.4, 3.5 and PyPy. 5. Schematics – Data Structure Validation.

Schematics is a Python library to combine types into structures, validate them, and transform the shapes of your data based on simple descriptions. The internals are similar to ORM type systems, but there is no database layer in Schematics. Instead, they believe that building a database layer is made significantly easier when Schematics handles everything but writing the query. Further, it can be used for a range of tasks where having a database involved may not make sense.

• View on Github – • Official Link – • Latest Version – v2.0.1 Some common use cases: • Design and document specific data structures • Convert structures to and from different formats such as JSON or MsgPack • Validate API inputs • Remove fields based on access rights of some data’s recipient • Define message formats for communications protocols, like an RPC • Custom persistence layers Installation of Schematics can easily be done via pip: Command: pip install schematics Schematics can also be install via Git: Command: git clone https://github.com/schematics/schematics.git 6.

Valideer – Lightweight extensible data validation and adaptation library. Valideer is a Lightweight data validation and adaptation library for Python. • View on Github – Features – • Supports both validation (check if a value is valid) and adaptation (convert a valid input to an appropriate output). • Succinct: validation schemas can be specified in a declarative and extensible mini “language”; no need to define verbose schema classes upfront.

• Batteries included: validators for most common types are included out of the box. • Extensible: New custom validators and adaptors can be easily defined and registered. • Informative, customizable error messages: Validation errors include the reason and location of the error. • Agnostic: not tied to any particular framework or application domain (e.g.

Web form validation). • Well tested: Extensive test suite with 100% coverage. To install Valideer, type the following command in your terminal: Command: pip install valideer Or install directly via Git utility: git clone https://github.com/podio/valideer cd valideer python setup.py install 7.

Voluptuous – A Python data validation library. Voluptuous, despite the name, is a Python data validation library. It is primarily intended for validating data coming into Python as JSON, YAML, etc. View on Github – Official Link – Latest Version – v0.10.5 Documentation Link – Some Features – • Validators are simple callables.

• Errors are simple exceptions. • Schemas are basic Python data structures. • Designed from the ground up for validating more than just forms. • Consistency.

Is there a library in python that can produce date dimensions given a certain day? I'd like to use this for data analysis. Often I have a time series of dates, but for aggregation purposes I'd like to be able to quickly produce dates associated with that day - like first date of month, first day in week, and the like. I think I could create my own, but if there is something out there already it'd be nice. Thanks time and datetime modules For some of your purposes you can use with method or with its method.

It allows you to pull, among other data: • number of the week of the year, • number of the weekday (you can also use for getting weekday number between 0 for Monday and 6 for Sunday), • year, • month, Which will suffice to calculate first day of the month, first day of the week and some other data. Examples To pull the data you need, do just: • to pull the number of the day of the week >>> from datetime import datetime >>> datetime.now().weekday() 6 • to pull the first day of the month use replace() function of datetime object: >>> from datetime import datetime >>> datetime.now() datetime.datetime(2012, 3, 3, 21, 41, 20, 953000) >>> first_day_of_the_month = datetime.now().replace(day=1) >>> first_day_of_the_month datetime.datetime(2012, 3, 1, 21, 41, 20, 953000) EDIT: As J.F.

Sebastian suggested within comments, datetime objects have weekday() methods, which makes using int(given_date.strftime('%w')) rather pointless.

I have updated the answer above.
