import re
# look for 'thing' in the string 'that thing'
match = re.search(r'thing', 'that thing')
# match.group() == 'thing'
# look for 'thig' in the string 'that thing'
match = re.search(r'thig', 'that thing')
# match == None
# . = any character except \n
match = re.search(r'..d+', 'abcdd')
# match.group() == 'bcdd'
