I was learning django and I dont understand what's happening here, what is the logic

Question

 if removepunc == "on":
    punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
    analyzed = ""
    for char in djtext:
        if char not in punctuations:
            analyzed = analyzed + char
    params = {'purpose':'Removed Punctuations', 'analyzed_text': analyzed}
    return render(request, 'analyze.html', params)

else:
    return HttpResponse("Error")

So basically this removes punctuations from a sentence and I'm not getting the loop part of the program. If anyone could explain, it would be great! Thanks

My advice is to learn Python's basics before trying Django. If you don't know how a basic loop works in a language, you'll be wasting your time with an advanced web framework. Learning the basics will take two-three days but it will save a lot of time going forward. — xyres, Jun 20 '22 at 18:55

you have djtext string which you scroll on with the for: for char in djtext

for example, if djtext='abc' then with for loop on it, char is 'a' in the first loop after 'b' after 'c'.

in this line if char not in punctuations, is checked that if char not into punctuations till concatenate char with analyzed string.

in the end:

    params = {'purpose':'Removed Punctuations', 'analyzed_text': analyzed}
    return render(request, 'analyze.html', params)

response data is getting ready then data that is params with analyze.html file return and render from django view.
