Select the correct answerWhy are local variable names beginning with an underscore discouraged?Optionsthey confuse the interpreterthey are used to indicate global variablesthey slow down executionthey are used to indicate a private variables of a class
Solution
The correct answer is "they are used to indicate a private variables of a class". In Python, a variable name starting with an underscore is used to indicate that it is a private variable of a class. This is not a hard and fast rule enforced by the Python interpreter (Python does not have true private variables), but it is a convention that is widely followed by Python programmers. Using an underscore at the start of a variable name in other contexts might confuse other programmers who read your code.
