findall function return all results instead the one specified in in IF clause in python

Here is my code

def ExtractTimeAndFrequency():

for line in ft.split('\r\n'):
    if 'cpu7' in line:
        tm = re.findall(r"([0-2][0-9]:[0-5][0-9]:[0-5][0-9])", ft)
        fr= re.findall(r"\d{7}", line)

return fr, tm
