python regex match numbers code example

Example 1: python regex numbers only

import re
re.compile(r'[/d]+') 
# /d refers to any digit
# use other regex patters for ore modifcations
# This can extract the numbers from the regex

Example 2: regex for digits python

[0-9] is not always equivalent to \d. In python3, [0-9] matches only 
0123456789 characters, while \d matches [0-9] and other digit characters, 
for example Eastern Arabic numerals.

Example 3: python re compile

import re
#	Compile a regular expression pattern into a regular expression object, which can be used for matching using its match(), search() and other methods, described below.

prog = re.compile(pattern)
result = prog.match(string)

#	is equivalent to

result = re.match(pattern, string)
