How can I print only integers/numbers from string

Hello I am fairly new at programming and python and I have a question.

How would I go about printing or returning only numbers from a string

For example:

"Hu765adjH665Sdjda"

output:

"765665"

a='a345g5'



for i in a:
    if int(i.isnumeric()):
        print(i,end=' ')

>>> s = "Hu765adjH665Sdjda"
>>> ''.join(c for c in s if c in '0123456789')
'765665'

You can use re.sub to remove any character that is not a number.

import re

string = "Hu765adjH665Sdjda"
string = re.sub('[^0-9]', '', string)
print string
#'765665'

re.sub scan the string from left to right. everytime it finds a character that is not a number it replaces it for the empty string (which is the same as removing it for all practical purpose).

Try filter

>>> str='1qaz2wsx3edc4rfv5tgb6yhn7ujm8ik9ol'
>>> print str
1qaz2wsx3edc4rfv5tgb6yhn7ujm8ik9ol
>>> filter(lambda x:x>='0' and x<='9', str)
'123456789'
