What is the difference between '==' and '=' in Python?

In Python, the symbols '==' and '=' serve distinct purposes, which is captured accurately in the first choice. The '==' operator is used to test for equality between two values or expressions, determining if they are equivalent in value. For example, if you have two variables and you want to check if their contents are the same, you would use '=='.

On the other hand, the '=' symbol is the assignment operator, which is employed to assign a value to a variable. When you use '=', you are putting a value into a variable for later use. For instance, executing x = 5 assigns the value 5 to the variable x.

This clear distinction is fundamental in programming with Python and is critical for correctly implementing conditional logic and variable management. Understanding how to properly use both operators is essential for writing effective and error-free code.
