If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setuptools, but will need to upgrade to the latest version:On Linux or macOS:pip install -U pip setuptoolsOn Windows:python -m pip install -U pip setuptoolsIf you’re using a Python install on Linux that’s managed by the system package manager (e.g "yum", "apt-get" etc…), and you want to use the system package manager to install or upgrade pip, then see: https://packaging.python.org/guides/installing-using-linux-tools/Otherwise:Download get-pip.py from https://bootstrap.pypa.io/get-pip.py. Run python get-pip.py. This will install or upgrade pip.Now you can use pip to install python packages. For example, ... Read More

A file containing Python code, definitions of statements, functions, or classes is known as a module. A module with the name "module" that we will construct is a file named module.py. To break down complex programmes into smaller, easier-to-understand parts, we use modules. Code reuse is another benefit of modules. In this article, we will discuss various ways to find which Python modules are being imported from a package. Using List Comprehension To iterate over each element in the Python list, a list comprehension is made out of brackets carrying the expression, which is then run for each element. Python ...

Working with complex programs that run for thousands of lines produces two fundamental problems arise – managing the code to know which functionality is implemented where and debugging the program in case of an error. Fortunately, both problems can be solved by breaking the code into multiple modules and then creating a single script file from the different modules. Python provides this exact functionality where different python modules can be bundled into a single executable script. This functionality allows for easy management and debugging of complex programs. Using zip One way of bundling multiple modules in python is by creating ... Read More

To make IntelliJ to recognize common Python modules, just create and add Python SDKFile -> Project Structure -> Project -> Project SDK -> newand select the installation path of your Python interpreter (for example, C:\Python26 in windows and /usr/bin/python2.7 in Linux) as the home path. This allows IntelliJ to look in these directories to give you suggestions and documentation hints.If your Python SDK is already properly configured and you are still facing the problem that builtins are not recognized, try this:File -> Invalidate Caches/Restart

You can uninstall a Python package on Windows by opening the Windows Command Prompt and entering the following command − pip uninstall module_name Uninstalling a package using pip Python's package manager is called PIP. In other words, it is a tool that enables us to install Python packages and dependencies (the software elements needed by your code to function without throwing any errors) that are not already available to us through the Python Standard Library. A computer language's tool that makes it simple to install any external dependencies is known as a package manager. Any package can be installed ... Read More

A file containing Python definitions and statements is referred to as a module. A module is a file that contains Python code; an “Program.py” file would be a module with the name “Program”. We utilise modules to divide complicated programs into smaller, more manageable pieces. Code reuse is also possible with modules. Instead of copying their definitions into several programs, we can define our most frequently used functions in a module and import it. Installing Python modules in Windows The Python package manager (pip) allows for the installation of modules and packages. Open a terminal and use the pip command ... Read More

In this article we will discuss how to list all the functions in a Python module. A Python module contains multiple different functions that allow for extensive code reusability making complex code simple. It also enhances portability of python program by changing platform dependent code into platform independent APIs Python standard library consists of modules written in C that provide access to system functionality and modules written in python that provide general solutions for everyday problems making the life of programmers easy as it prevents writing of long code for simple problems Using dir() to get functions in a module ...

json is simplejson, added to the stdlib. But since json was added in 2.6, simplejson has the advantage of working on more Python versions (2.4+).simplejson is also updated more frequently than Python. Although they are the same, the version included in the stdlib doesn't include the latest optimizations. So if you need (or want) the latest version, it's best to use simplejson itself, if possible.A good practice, is to use one or the other as a fallback. For example,try: import simplejson as json except ImportError: import json

Many a times it is required to treat more than one statements in a program as a block. Different programming languages use different techniques to define scope and extent of block of statements in constructs like class, function, conditional and loop. In C and C++ for example, statements inside curly brackets are treated as a block. Python uses uniform indentation to mark block of statements.Before beginning of block symbol : is used. First and subsequent statements in block are written by leaving additional (but uniform) whitespace (called indent) . In order to signal end of block, the whitespace is dedented. ... Read More

Reserved words (also called keywords) are defined with predefined meaning and syntax in the language. These keywords have to be used to develop programming instructions. Reserved words can’t be used as identifiers for other programming elements like name of variable, function etc.Following is the list of reserved keywords in Python 3andexceptlambdawithasfinallynonlocalwhileassertfalseNoneyieldbreakfornotclassfromorcontinueglobalpassdefifraisedelimportreturnelifinTrueelseistryPython 3 has 33 keywords while Python 2 has 30. The print has been removed from Python 2 as keyword and included as built-in function.To check the keyword list, type following commands in interpreter −>>> import keyword >>> keyword.kwlist
