re python code example

Example 1: python regular expression

import re

# The string you want to find a pattern within
test_string = 'Hello greppers!'

# Creating a regular expression pattern
# This is a simple one which finds "Hello"
pattern = re.compile(r'Hello')

# This locates and returns all the occurences of the pattern
# within the test_string
match = pattern.finditer(test_string)

# Outputs all the ocurrences which were returned as 
# as match objects
for match in matches:
  print(match)

Example 2: re python3

import re
>>> m = re.search('(?<=abc)def', 'abcdef')
>>> m.group(0)
'def'

Example 3: python re

if pattern := re.search("[iI] am (.*)", "I am tired"):
    print(f"Hi {pattern.group(1)}, I'm dad!")

Example 4: python re

m = re.search(r'[cbm]at', 'aat')
print(m)

Example 5: python re
