Python SyntaxError: Invalid Character in Identifier - Explained

This error occurs when a character that is not allowed in Python identifiers is used. Python identifiers can only contain letters (a-z, A-Z), digits (0-9), and underscores (_), and they cannot begin with a digit.

For example, the following code will raise a SyntaxError:

my-variable = 10

This is because the hyphen (-) is not allowed in Python identifiers. To fix this error, you can replace the hyphen with an underscore:

my_variable = 10
