Python | Remove the given substring from end of string
Sometimes we need to manipulate our string to remove extra information from string for better understanding and faster processing. Given a task in which substring needs to be removed from the end of the string. Given below are a few methods to solve the given task.
Method #1: Using Naive Method
# Python3 code to demonstrate# to remove a substring from end of the string # Initialising stringini_string = 'xbzefdgstb' # initializing stringsstring = 'stb' # printing initial string and substringprint ("initial_strings : ", ini_string, "\nsubstring : ", sstring) # removing substring from end# of string using Naive Methodif ini_string.endswith(sstring): res = ini_string[:-(len(sstring))] # printing resultprint ("resultant string", res) |
Output:
initial_strings : xbzefdgstb substring : stb resultant string xbzefdg
Method #2: Using sub() method
# Python3 code to demonstrate# to remove a substring from end of string import re # Initialising stringini_string = 'xbzefdgstb' # initializing stringsstring = 'stb' # printing initial string and substringprint ("initial_strings : ", ini_string, "\nsubstring : ", sstring) # removing substring from end# of string using sub Methodif ini_string.endswith(sstring): res = re.sub(sstring, '', ini_string) # printing resultprint ("resultant string", res) |
Output:
initial_strings : xbzefdgstb substring : stb resultant string xbzefdg
Method #3: Using replace() method
# Python3 code to demonstrate# to remove a substring from end of string # Initialising stringini_string = 'xbzefdgstb' # initializing stringsstring = 'stb' # printing initial string and substringprint ("initial_strings : ", ini_string, "\nsubstring : ", sstring) # removing substring from end# of string using replace Methodif ini_string.endswith(sstring): res = ini_string.replace(sstring, '') # printing resultprint ("resultant string", res) |
Output:
initial_strings : xbzefdgstb substring : stb resultant string xbzefdg
