When we are developing a large Python program, it is a good practice to place all the user-defined exceptions that our program raises in a separate file. Many standard modules define their exceptions separately asexceptions.pyorerrors.py(generally but not always). Example: Python User-Defined E...
In other programming languages, we can define a specific set of values. To define infinity, we can use float("inf") to define a positive infinite number and for a negative infinite number, we use float("-inf"). Now, we will look at how it works in Python. Suppose we have a value...
A Python function should always start with the def keyword, which stands for define. Then we have the name of the function (typically should be in lower snake case), followed by a pair of parenthesis() which may hold parameters of the function and a semicolon(:) at the end. ...
Functions in Python are blocks of reusable code that perform a specific task. You can define your own functions and use built-in Python functions. We have a course onwriting functions in Pythonwhich covers the best practices for writing maintainable, reusable, complex functions. ...

Python uses indentation to define blocks of code. Missing indentation will cause an error. Example: ifTrue:print("This will cause an error!")# IndentationError Copy Fixed Example: ifTrue:print("This will not cause an error!") Copy
We need to define the function before calling it to fix this error. Avoid Using Misspelled Variables or Function Names in Python Another reason to get this error is when a user is making mistakes in defining the correct spelling of a function; that is why the user is getting this type of...
In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
