Identify invalid variable names from the following, giving reason for each: Group, if, total marks, S.I., volume, tot_strength, #tag, tag, 9a, for

1. Group — This is a valid variable name. 2. if — This is an invalid variable name because if is a reserved keyword in Python and cannot be used as a variable name. 3. total marks — This is an invalid variable name because it contains a space, which is not allowed in variable names. A variable name must be a single continuous string without spaces. 4. S.I. — This is an invalid variable name because it contains full stops, which are not allowed in variable names. Variable names can only include letters, digits, and underscores. 5. volume — This is a valid variable name. 6. tot_strength — This is a valid variable name. 7. #tag — This is an invalid variable name because it starts with a hash symbol (\#), which is not allowed in variable names. Variable names must start with a letter or underscore. 8. tag — This is an invalid variable name because it contains a dollar sign (), which is not allowed in variable names. Variable names can only include letters, digits, and underscores. 9. 9a — This is an invalid variable name because it starts with a digit, which is not allowed in variable names. Variable names must start with a letter or underscore. 10. for — This is an invalid variable name because for is a reserved keyword in Python and cannot be used as a variable name.
