search() in regex in python by R4R Team

- search() is a python regex function that searches the string for a match, and returns a Match object if there is a match.

Syntax-

re.search(pattern,string)

-Here pattern is everything that you want to search in the string, metacharacters are also used in making pattern.

Example-

string is s="This is online"
then re.search("is",s)
it will search the 'is' in the given string and match will be found successfully.


program-

import re

#Check if the string starts with "This" and ends with "string":
s= "This is the amazing string"
x = re.search("^This.*string$", s)
if (x):
print("We have a match!")
else:
print("No match")


s= "The amazing string"
x = re.search("^This.*string$", s)
if (x):
print("We have a match!")
else:
print("No match")

output-

We have a match!
No match

-In this program, we have a string "This is the amazing string", and we check that string is starts with 'This' and ends with 'string'
-so "^This.*string$" shows that our required string is starts with 'This', in between every thing is acceptable, and 'string' is in the end.
- '^' shows the starting , '$' shows the ending and '.*' shows between.
