how to use regex to search for a float pattern inside a list

So I have the following list of data:

lst_text = ['---', 'Project-Desc: kytos/kytos-end-to-end-tester', 'Last-Status: failed', 'pytest summary:  12 failed, 49 passed in 2919.10 seconds ']

I need to extract the "2919.10 seconds" from there.

I have this code :

summary = re.findall(r"\d+ \w+", lst_text[3])

So far, the regex that extracts the summary does not account for decimal points and also expects a space between a number and word. That current line of code just returns "10".

However, I need to recheck the regex expression, so that it also includes floating point numbers.

Any suggestions?

To get the floating point value followed by the word after from the fourth item in the list:

\b\d+\.\d+\s+\w+
  • \b A word boundary to prevent a partial match
  • \d+\.\d+ Match 1+ digits, a . and 1+ digits
  • \s+\w+ Match 1+ whitespace chars and 1+ word chars

Updated example code

import re
lst_text = ['---', 'Project-Desc: kytos/kytos-end-to-end-tester', 'Last-Status: failed', 'pytest summary:  12 failed, 49 passed in 2919.10 seconds ']
summary = re.findall(r"\b\d+\.\d+\s+\w+", lst_text[3])
print(summary)

Note that \w can also match a digit, so 2919.10 12345 would for example also match.

Output

['2919.10 seconds']
