How to extract numbers from text using Python regular expression?

If we want to extract all numbers/digits  individually from given text we use the following regex

Example

import re
s = '12345 abcdf 67'
result=re.findall(r'\d', s)
print result

Output

['1', '2', '3', '4', '5', '6', '7']

If we want to extract groups of numbers/digits from given text we use the following regex

Example

import re
s = '12345 abcdf 67'
result=re.findall(r'\d+', s)
print result

Output

['12345', '67']
