如何从Python中的import语句知道包或模块名称？

Question

I have a python file and the developer of that code has left the organization. When I run the code I get the following error.

import dataAnalysis as DV ModuleNotFoundError: No module named 'dataAnalysis'

I provide below the brief snippet of the python file "main.py" below.

import dataAnalysis as DV

def performCheck():
    ... other code
    ... other code
    i = DV.addGraph( pathplus)

Here my question is , how to know the actual module or package name of "dataAnalysis" from the above import statement so that I can make "pip install ". However, I tried to install DataAnalysis module, still it does not work.

Is there any way to get the module or package name to install from the import statement in python ?

Answer 1

Go to console or terminal and run command pip install dataAnalysis . If permission denied, then make sure you have enough privilege to install a package.

Update : In my opinion pip package DataAnalysis is a library that can be used for pre-processing a csv file. As per your given code, it looks like adding a graph so may be it could be a local package. Check dataAnalysis folder in your project with __init__.py file inside.
