为每个项目重复相同的用户输入 - python

Question

I am in the process of writing a KWIC search engine. I want to let the user decide how many words should be displayed before and after the hit word (range). I have managed this so far, but the range is asked for again after every single hit. Do you know how I can let the user select the range only once, and then it will be used for all hits? Here is the part it is about:

def displayKWIC (text, wordPos):

    global textSequence
    resultline = ''
    ranges =(int(input("Bitte geben Sie ein Range: ")))
    for i in range(max(0,wordPos-ranges), min(len(textSequence[text]),wordPos+ranges)):
        resultline += ' '+ textSequence[text][i]  
    print(text+': =>'+resultline,"\n", "\n")
    return

I assume the problem is somewhere in the ranges line.

Thanks in advance:)

Answer 1

The user is asked for ranges after every single hit, since ranges is assigned within displayKWIC . Because of this, every time displayKWIC (text, wordPos) is called, ranges is assigned anew.

To change this, you could assign ranges outside of displayKWIC and pass it to the function as an argument, alongside text and wordPos .
