Proper naming of the Python variables is very important for writing clean, readable, and maintainable Python code. Here we have mentioned the important rules that simply ensure that your code runs without errors. 1. Start with a Letter or Underscore (_) The name of every variable in Python ...
Defining Python functions: Syntax and naming rulesIn Python, you can define a function using the "def" keyword followed by the function name, parentheses containing optional parameters, and a colon. Function bodies, which contain the code to be executed when the function is called, are indented...

The naming of variables is quite flexible, but there are some rules you need to keep in mind: Variable names must only be one word (as in no spaces) Variable names must be made up of only letters, numbers, and underscore (_)
Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face ofambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. ...
