\b python code example

Example 1: python regex search group

>>> m = re.match(r"(\w+) (\w+)", "Isaac Newton, physicist")
>>> m[0]       # The entire match
'Isaac Newton'
>>> m[1]       # The first parenthesized subgroup.
'Isaac'
>>> m[2]       # The second parenthesized subgroup.
'Newton'

Example 2: python b before string

# It means it's a byte string.
# Which means it'll just print b'string' if you try to print it out
string = b'Random string'
print(string)
string_without_b = string.decode()
print(string_without_b)
