Python NameError: 'python' is not defined - 解决方法

The error message "NameError: name 'python' is not defined" suggests that there is a problem with the code in the file "main.py". It seems that the code is trying to reference a variable or function named 'python' which is not defined.

To resolve this issue, you need to review the code in "main.py" and ensure that all variables and functions are properly defined before they are used. Make sure that the variable 'python' is declared and assigned a value before it is referenced in the code.
