Extracting the date from a .txt file
I have a .txt file. It contains a few dates. The one I'm looking is preceded by words: "Date: dd.MM.yy Hour: HH:mm". I tried to match it by
matches=re.findall(r'Date:sdd.dd.d{4}sHour:sdd:dd', text)
but I need to extract only numbers in specific format- "dd.MM.yy HH:mm". The file contains also a few other dates- I don't see another way to match it tha. Now I'm obviously getting "Date: 28.10.2018 Hour: 11:00".
1) Is there a better way to search in the .txt file?
2) How to extract both date and hour from the string, omitting words?

You should use capture groups to get the information you're interested in:
import re
s = "Date: 11.19.2018 Hour: 15:23"
matches = re.findall(r'Date: (d{2}.d{2}.d{4}) Hour: (d{2}:d{2})', s)
The variable matches will then contain:
[('11.19.2018', '15:23')]

if you use a group for each number you can get directly the individual numbers to build properly a Date, e.g.r'Date: (d{2}).(d{2}).(d{4}) Hour: (d{2}):(d{2})'
