how to display the print message from the function imported from another file when called from inside an if block

I create a python function in a file and filename is ifunc.py

def func():
    print('print something')

I have my main program in another file like this:

import ifunc

inputFlag = input('input something:')

if inputFlag == 1:
    ifunc.func()

and this produce nothing, but when I try to import the function outside the if statement like:

import ifunc
ifunc.func()

the print message print something will show up.

So how could I make the print message show up when the called function inside the if statement?

Please give me some advice.
Thanks in advance!
