I have the following string:
How can I get the last four characters and store them in a string using Python?
str = "aaaaabbbb" newstr = str[-4:]
>>> mystr = "abcdefghijkl" >>> mystr[-4:] 'ijkl'
This slices the string’s last 4 characters. The -4 starts the range from the string’s end. A modified expression with
[:-4] removes the same 4 characters from the end of the string:
>>> mystr[:-4] 'abcdefgh'
For more information on slicing see this Stack Overflow answer.
