How do I make a string if it is greater than n characters then leave only the last 50 characters?

Question

text = "hi, hello! hello! I have a cat hello! the fire burns 88988° the planes are sooo fast" #Exmple string

print(len(text))

if(len(text) > 20):
    #text = text[:-10]
    t_len = len(text) +(-len(text) - 10)
    text = text[:-t_len]

print(len(text))
print(text)

I was trying with several things but what I need is that if len (string)> n then extract me and save the last 50 characters in another variable

Does this answer your question? [How do I get a substring of a string in Python?](https://stackoverflow.com/questions/663171/how-do-i-get-a-substring-of-a-string-in-python) — Jab, Sep 21 '21 at 20:41
I wanted to extract the last 50 characters, which would remove the last 50 characters. Just leave those last 50 characters — Electrisik Vocal, Sep 21 '21 at 20:44
In your example code, what do you want it to print? Add the desired output to the question. — Barmar, Sep 21 '21 at 20:49
@Barmar told you how to do that first thing. And you don't eve have to test; if the string is less than 50 characters, that will return the whole string. — Tim Roberts, Sep 21 '21 at 20:49
@TimRoberts Except that the test seems to be different from the number he wants to extract. It's the last 50, not the last n. — Barmar, Sep 21 '21 at 20:51

If I understand correct you need something like this:

def extractor(n, string):
    output = ""
    if len(string) > n:
        newstring = string[-50:]
        output = output + newstring
    return output

If you want to only return something id it has more then n, or you want to return the whole string if len(string) > 51. Then you could add an else statement or change the function, but the thing you are asking is solved in the above function.

Really thanks for the help – Electrisik Vocal Sep 21 '21 at 22:51 — Electrisik Vocal, Sep 21 '21 at 22:51
