SyntaxError: invalid character in identifier

This error occurs when you use an invalid character in a variable or function name. In Python, identifiers can only contain letters, numbers, and underscores. They cannot start with a number and cannot contain spaces or special characters like punctuation marks.

For example, if you try to create a variable with a name that contains a hyphen:

my-variable = 10

You will get a syntax error:

SyntaxError: invalid character in identifier

To fix this error, you should use only valid characters in your variable or function names. You can use underscores instead of hyphens, or you can use camel case to separate words within the name. For example:

my_variable = 10
myVariable = 10
