Comparison of string lookup efficiency in Python

There are several ways to find a string in Python, usually with Re.match/search or Str.find

Use an example to illustrate the efficiency of the various methods as follows:

From Timeit import Timeitimport redef Find (String, text):    if String.find (text) >-1:        passdef re_find (string, t EXT):    if Re.match (text, string):        passdef Best_find (String, text):    if text in string:       passprint Timeit ( "Find (String, text)", "from __main__ import find; string= ' Lookforme '; text= ' look ')  print Timeit ("Re_find (string, Text)", "from __main__ import re_find; string= ' Lookforme '; text= ' look ')  print Timeit ("Best_find (string, Text)", "from __main__ import best_find; string= ' Lookforme '; text= ' look ')

The result of the execution is:

The most efficient way to see it is: if text in string:
