I wanted to ask if there is any way of finding a sequence of characters from a bigger string in python? For example when working with urls i want to find www.example.com from http://www.example.com/aaa/bbb/ccc. If found, it should return True.
Or is there any other way to do so? Thanks in advance!
Use in to test if one string is a substring of another.
>>> "www.example.com" in "http://www.example.com/aaa/bbb/ccc"
True
I'm showing another way to do this
>>> data = "http://www.example.com/aaa/bbb/ccc"
>>> key = "www.example.com"
>>> if key in data:
... #do your action here
There are number of ways to do it:
>>> a = "http://www.example.com/aaa/bbb/ccc"
>>> b = "www.example.com"
>>> if a.find(b) >=0: # find return position of string if found else -1
... print(True)
...
True
>>> import re
>>> if re.search(b,a):
... print(True)
...
True
