Python error “importerror: no module named” in Python Programming Language?

Ah, this is a very common problem. Do not worry. I see this error many times. It means Python cannot find the library or module you want to use.

Most of the time, the reason is simple. The module is not installed on your computer. You can fix this with pip, the Python package manager. Open your terminal or command prompt and type: pip install module_name. You must replace module_name with the real name of the library you need.

Sometimes, the problem is just a small mistake in your code. Check the name you write. A small typo, like import requsts instead of import requests, will make this error.

Another thing can be your Python environment. Maybe you have many Pythons? One for your project, one for the system? The module can be installed in one Python, but you run your script with another one. This happens a lot. You can type pip list in your terminal to see all modules installed in the current environment.

And a last tip, a classic trap! Do not name your own file the same as the module. For example, if you make a file pandas.py and then you write import pandas inside, Python gets confused. It tries to import your own file.

I hope this helps you. It is usually one of these simple things.
