I want to remove the first part of this string however the number changes

Question

I want to remove the first 3 numbers of any string that I put in the input.

response = input("Insert String: ")

If I were to put any string in the response it would print it with the first 3 characters removed.

number or character? What if the input is `'abc12d34e5'`? – mozway Jun 13 '22 at 11:13 — mozway, Jun 13 '22 at 11:13

You can use string slicing.

response=input("Insert string:")[3:]

Try:

response = input("Insert String: ")
prefixStr = response[:2]
last_3_chars = response[-3:]
print(last_3_chars, prefixStr, sep='\t')

Maybe? I'm not sure exactly what you mean. Please clarify your request.

The request is pretty clear tbh. – matszwecja Jun 13 '22 at 11:15
Just a note, this contains a mistake - `first_3_chars` will actually only be the first two chars. – iteratedwalls Jun 13 '22 at 11:19
@iteratedwalls apologies, you are correct. I will replace with `prefixStr` – Anony Mous Jun 13 '22 at 11:20
Now `last_3_chars` is undefined, and it's still the first two characters. Also, why do you need the tab sep? Python will automatically separate arguments to `print` with spaces. – iteratedwalls Jun 13 '22 at 11:21
Firstly, do you mean `first_3_chars`? And secondly, I prefer `'\t'` especially in a debug environment. Just personal preference. But yes, I see what you mean. I just prefer it, it's generally just more comfortable and easier to see, especially with large projects. – Anony Mous Jun 13 '22 at 11:24
