Which of the following is true about Python variables?

In Python, variable names are used to identify data stored in memory, and they adhere to specific rules regarding their formation. One of the fundamental rules is that variable names cannot be the same as Python keywords. Keywords are predefined identifiers that have special meanings in the language, such as 'if', 'else', 'while', and 'def'. Allowing variable names to be the same as keywords would create confusion and impair the readability of the code, as the interpreter would not be able to distinguish between a variable and its intended use as a control statement or function.

This rule ensures clear communication of intentions within the code and prevents syntax errors. Using keywords as variable names may lead to errors or unexpected behavior in a program, highlighting the significance of this restriction in creating robust and maintainable code. Hence, it is crucial for developers to be aware of the keywords in Python to avoid naming conflicts when defining their variables.
