How to extract numbers from a string in Python?

Question

I would extract all the numbers contained in a string. Which is the better suited for the purpose, regular expressions or the isdigit() method?

Example:

Answer 1

line2 = "hello 12 hi 89"
temp1 = re.findall(r'\d+', line2) # through regular expression
res2 = list(map(int, temp1))
print(res2)

Hi ,

you can search all the integers in the string through digit by using findall expression .

In the second step create a list res2 and add the digits found in string to this list

hope this helps
