python regex pattern match code example
Example 1: python pattern matching example
import re
pattern = re.compile('[a-zA-Z ]+') # a...z A...Z and space allowed

Example 3: python re.search()
## Search for pattern 'bb' in string 'aabbcc'.
## All of the pattern must match, but it may appear anywhere.
## On success, match.group() is matched text.
match = re.search(r'bb', 'aabbcc') # found, match.group() == "bb"
match = re.search(r'cd', 'aabbcc') # not found, match == None
## . = any char but \n
match = re.search(r'...c', 'aabbcc') # found, match.group() == "abbc"
## \d = digit char, \w = word char
match = re.search(r'\d\d\d', 'p123g') # found, match.group() == "123"
match = re.search(r'\w\w\w', '@@abcd!!') # found, match.group() == "abc"
