[FIXED] How to find any number both integer/decimal in a string with regex (python)

Issue

I want to pick numbers from these strings both integers and decimals with regex in one line command for each.

string="./folder300.5/file300.5"
string2="./folder300/file300"

i want the following output after applying regex for both strings :

300.5
300

Solution

As mentioned in the comment, there's two numbers in each string, but assuming they are always the same as in your examples, you could try:

\d*\.?\d+$

\d*      Match multiple numbers
\.?      Match dot if present (needed for decimals)
\d+      Match numbers following dot
$        End of string - at least one digit required at the end of your string

You can play with it here.

For example:

import re

string="./folder300.5/file300.5"
string2="./folder300/file300"
regex = "\d*\.?\d+$"
x = re.search(regex, string)
y = re.search(regex, string2)
print(x.group(0)) # 300.5
print(y.group(0)) # 300
