print() prints only every second input

I'm new to python and I've been trying to make a little function to call upon when I need to filter an input from everything except regular letters.

I've used SO for parts of the code, but I can't seem to understand why does it only print on every second try.

Here's my code:



import re

i=1



def inputFilterText():

    inputRaw = input('input: ')

    inputFiltered = re.sub('[^a-zA-Z]+', '', inputRaw)

    return inputFiltered



while i > 0:

    inputFilterText()

    print(inputFilterText())


And here's my output:



output



I'm not really sure what's going on, but I presume it's a logical error. I've only just started using Python so any help is appreciated.



PS
The 'while' is only there so it's easier to test, it can be omitted.

You are calling inputFilterText twice. Once within the print() and once before. This is causing the code to prompt for input twice before printing the second response.

Might I suggest using a variable here, you're not doing anything with the first filter call (this is why it's asking the first time) and the second one you're only printing.



while True:

    txt = inputFilterText()

    #do some stuff if needed

    print(txt)
