'abcd'# Python program to extract digits from string
# take string
string = "kn4ow5pro8am2"
# print original string
print("The original string:", string)
# using join() + filter() + isdigit()
num = ''.join(filter(lambda i: i.isdigit(), string))
# print extract digits
print("Extract Digits:", num)>>> import re
>>> string1 = "498results should get"
>>> int(re.search(r'\d+', string1).group())
498>>> str = "h3110 23 cat 444.4 rabbit 11 2 dog"
>>> [int(s) for s in str.split() if s.isdigit()]
[23, 11, 2]
>>> txt = "h3110 23 cat 444.4 rabbit 11 2 dog"
>>> [int(s) for s in txt.split() if s.isdigit()]
[23, 11, 2]
