If I remember my QBasic, right, left and mid do something like this:
>>> s = '123456789'
>>> s[-2:]
'89'
>>> s[:2]
'12'
>>> s[4:6]
'56'

Python - Right and Left Shift characters in String - GeeksforGeeks
July 12, 2025 - s = "geeksforgeeks" k = 17 n = len(s) k %= n l = s[k:] + s[:k] r = s[-k:] + s[:-k] print("Left Shift:", l) print("Right Shift:", r) ... k %= n reduces unnecessary full rotations. Shifting a 13-character string by 17 is the same as shifting by 4 (since 17 % 13 = 4). Slicing is then used to perform the shifts. Deque (double-ended queue) from the collections module is designed for efficient rotations and manipulations. This method uses the built-in rotate function of deque for shifting characters.

You're looking for slicing:
>>> s = "Hello World!"
>>> print s[2:] # From the second (third) letter, print the whole string
llo World!
>>> print s[2:5] # Print from the second (third) letter to the fifth string
llo
>>> print s[-2:] # Print from right to left
d!
>>> print s[::2] # Print every second letter

So for your example:
>>> s = 'col555'
>>> print s[3:]
555

If you know it will always be col followed by some numbers:
>>> int('col1234'[3:])
1234
