Python is a flexible and versatile programming language that can be leveraged for many use cases, with strengths in scripting, automation, data analysis, mac…
As soon as we set a variable equal to a value, weinitializeor create that variable. Once we have done that, we are set to use the variable instead of the value. In Python, variables do not need explicit declaration prior to use like some programming languages; you can start using the ...

One major change was the syntax between the two languages, with Python 3’s syntax now integrating built-in commands into its code, side-stepping the need to create functions as required in Python 2. There were many further alterations to the language, which can be summarized by saying the ...
The function opens the file whose name is provided in its parameter. Then it applies thereadlines()method, which returns a Python list containing the lines of the file as its elements. That list is saved to thewordsvariable and returned by the function. ...
Python Compare Strings We can compare Strings in Python using Relational Operators. These operators compare the Unicode values of each character of the strings, starting from the zeroth index till the end of the strings. According to the operator used, it returns a boolean value. print(“Python...
We will use np.where() for this purpose and pass our specific condition to create a mask of values.Let us understand with the help of an example,Python program to turn a boolean array into index array in numpy# Import numpy import numpy as np # Creating a numpy array arr = np.arange...
It returns the boolean value, True or False, of a given variable in Python. The boolean values of the numbers 0 and 1 are set to False and True as default in Python.So, using the not operator on 1 returns False, i.e., 0. Also, note that the not operator can be used in the ...
The collections and itertools modules from the Python standard library provide a couple of useful tools that allow you to iterate through multiple dictionaries in one go. In collections, you’ll find the ChainMap class, which allows you to create a dictionary-like object by combining multiple exis...
There’s no limit on how many modules you put in the templatetags package. Just keep in mind that a {% load %} statement will load tags/filters for the given Python module name, not the name of the app. To be a valid tag library, the module must contain a module-level variable nam...
