Question
Which of the following is an invalid variable name in Python?Marks: 1_my_var. 2ndVarmyVarmy_var_2
Solution
The invalid variable name in Python from the given options is "2ndVar". In Python, variable names cannot start with a number. They must start with a letter (a-z, A-Z) or an underscore (_). Therefore, "2ndVar" is not a valid variable name in Python. The other options "1_my_var", "myVar", and "my_var_2" are all valid variable names.
