On Python 3.9 and newer you can use the removeprefix and removesuffix methods to remove an entire substring from either side of the string: url = 'abcdc.com' url.removesuffix('.com') # Returns 'abcdc' url.removeprefix('abcdc.') # Returns 'com' The relevant Python Enhancement Proposal is PEP-616. On Python 3.8 and older you can use endswith and ...
67. If you want to find out whether a whole word is in a space-separated list of words, simply use: def contains_word(s, w): return (' ' + w + ' ') in (' ' + s + ' ') contains_word('the quick brown fox', 'brown') # True. contains_word('the quick brown fox', 'row') # False. This elegant method is also the fastest.

Oct 1, 2016 · All string characters are unicode literal in Python 3; as a consequence, since str.split() splits on all white space characters, that means it splits on unicode white space characters. So split + join syntax (as in 1 , 2 , 3 ) will produce the same output as re.sub with the UNICODE flag (as in 4 ); in fact, the UNICODE flag is redundant here (as in 2 , 5 , 6 , 7 ).
Here is all you have to do to make a new-style class: you use the Python syntax to say that it inherits from "object". You do that by putting parentheses after the class name and putting the name object inside the parentheses. Like so: class CallMe(object): # Class. def App(): # Method one.
The Python documentation notes the difference between the three methods. str.isdigit. Return true if all characters in the string are digits and there is at least one character, false otherwise. Digits include decimal characters and digits that need special handling, such as the compatibility superscript digits.
Solution #1: Python builtin. use SequenceMatcher from difflib. pros: built-in python library, no need extra package. cons: too limited, there are so many other good algorithms for string similarity out there. example: >>> from difflib import SequenceMatcher >>> s = SequenceMatcher(None, "abcd", "bcde") >>> s.ratio() 0.75 Solution #2: jellyfish ...

Aug 9, 2010 · The find() method should be used only if you need to know the position of sub. To check if sub is a substring or not, use the in operator. (c) Python reference. +1 for highlighting the gotchas involved in substring searches. the obvious solution is if ' is ' in s: which will return False as is (probably) expected.
