SyntaxError:", line 26 ` ^ SyntaxError: invalid syntax

Hello Streamlit team

File "D:\anaconda3\envs\FMPython\lib\site-packages\streamlit\runtime\scriptrunner\", line 565, in _run_script
    exec(code, module.__dict__)File "E:\streamlit_programs\ML\", line 12, in <module>
    import download

Following code generates the above error, although it was working before, is present, why it shows syntax error?

Is the app running locally or is it deployed somewhere?

FWIW your code compiles here without issues.
