Question
Select the correct answerWhich of the following is true for variable names in Python?Optionsunlimited lengthunderscore and ampersand are the only two special characters allowednone of the mentionedall private members must have leading and trailing underscores
Solution
The correct answer is "unlimited length". In Python, variable names can be of any length. However, they must start with a letter or an underscore and cannot start with a number. They can contain letters, numbers, and underscores. Special characters like ampersand are not allowed. Also, there is no requirement for private members to have leading and trailing underscores, although it is a common convention to use a leading underscore for non-public attributes or methods.
