Which of the following statements is/are correct for variable names in...
Variable names in Python language have certain rules and restrictions. Let's analyze each option to determine which statement(s) is/are correct.
a) All variable names must begin with an underscore.
This statement is incorrect. In Python, variable names can start with either a letter (a-z, A-Z) or an underscore (_). However, it is a convention to use an underscore at the beginning of a variable name to indicate that it is intended to be private or for internal use only.
b) Variable names can be of any length.
This statement is correct. Python allows variable names of any length. However, it is recommended to keep the variable names meaningful and concise for better code readability.
c) The variable name length is a maximum of 2.
This statement is incorrect. Python does not impose any maximum limit on the length of variable names. They can be as long as needed.
d) All of the above.
Since options a and c are incorrect, the correct answer is option 'B' - Variable names can be of any length.
To summarize, in Python, variable names can start with a letter or an underscore, they can be of any length, and there is no maximum limit on the length of variable names. It is important to choose meaningful and descriptive variable names to make the code more readable and understandable.
