Tokens are generated by the Python tokenizer, after reading the source code of a Python program. It breaks, the code into smaller parts. The tokenizer ignores whitespace and comments and returns a token sequence to the Python parser. The Python parser then uses the tokens to construct a parse...
some programming languages, such as python and ruby, do not require semicolons at the end of each statement. this is because these languages use whitespace to determine the end of a statement instead of a semicolon. while this can make the code look cleaner, it can also lead to errors ...
