python : regex to remove alphanumeric character from the string at the end

Question:

Regex to remove alphanumeric character from this string "calico-typha-66f59c4ff4" at the end

in python

Solution:

You can use the regular expression module re in Python to remove the alphanumeric characters

at the end of the string "calico-typha-66f59c4ff4".

Here is an example of how to do it:

%%%%%%%%%%%

import re

string = "calico-typha-66f59c4ff4"

regex = r'\w+$' # matches one or more alphanumeric characters at the end of the string

result = re.sub(regex, '', string)

print(result) # output: calico-typha-

%%%%%%%%%%%%%

In this example, the re.sub() function replaces the matched pattern (\w+$) with an empty

string, effectively removing the alphanumeric characters from the end of the string.

Explanation :

    \w : Matches any alphanumeric character; this is equivalent to the                      class [a-zA-Z0-9_].

$ :  Matches at the end of a line, which is defined as either the end of the string, or any location followed by a newline character.
