NameError: name 'jinja2' is not defined

Python Help
1

I’m working on a Python project using Jinja2 templates within a virtual environment. The project structure is set up properly, and the virtual environment (new_env) is activated. The Jinja2 library is installed, and testing shows it imports successfully when executed as a standalone script. However, when I run main.py, I get the error:

NameError: name ‘jinja2’ is not defined

Despite verifying that jinja2 is installed in the virtual environment and that the Python executable from the virtual environment is being used, the error persists.

Steps Taken:

  1. Activated the virtual environment and confirmed its path.

  2. Verified that Jinja2 imports correctly in isolation.

  3. Checked that main.py and all necessary files (like templates) are in the correct project directory.

  4. Attempted to run main.py directly using the virtual environment’s Python interpreter, but the error remains.

Request for Assistance

Has anyone experienced an issue where a library imports fine in a standalone script but fails when called from within the main project file?

Could this be an issue with the environment path, file structure, or a potential conflict with Python versions?

Any other suggestions for troubleshooting this persistent NameError would be greatly appreciated
I know i created multiple lines with same codes

The name error occurs in line 3 of the code_generator module. In the code you show, line 3 is an empty line. You are running different code, you need to find out where that is coming from. From what you have submitted , we cannot see what code is actually running.
