Conditional import a module in python with if-statement

Question

I have a code in production that requires to read certain modules if a parameter is given 1 and should not read certain modules if a parameter is zero. Here is a simple example:

global parameter
if parameter==0: 
   import numpy as np 

if parameter ==1:
   import pandas as pd

Is there anyway to achieve this in python? I cannot import both modules at the same time.

Yes, you can. Only you have to keep in mind to indent the code accordingly — , Jul 27 '21 at 02:09
can you please give an example? Does it work the way I write in my question? I thought i could not import like that — user2512443, Jul 27 '21 at 02:11
When I copy and paste your code, it works. What problem are you having with it? — Mark, Jul 27 '21 at 02:13

Importing Pandas will cause Numpy to be imported behind the scenes, FWIW. — Karl Knechtel, Jan 19 '23 at 04:21

The code you have here must work properly as is.

I don't understand what this means: that the OP's code as shown already works, or that it doesn't but it should? – smci Jul 27 '21 at 02:24
sorry I never tested it myself because I never though this would work. Anyhow, thanks for clarification. – user2512443 Jul 27 '21 at 16:25
@smci my appologies for being unclear. Yes, it works as is – jalovisko Jul 27 '21 at 18:04
