Answer 1

You can use \n.

For example: if you do print(“foo \nbar”) foo is line one, bar is line two.

Answer 2

You can use the next function on the file object to obtain the next line:

for x in fp:
    if 'States' in x.split():
        print(next(fp), end='')

Answer 3

You may not pick this solution as I don't know whether you can use regex or not but you can use regex to get the matching result. I don't know what the use case actually is but assuming you only have those lines in a text file, the regex States\n(.*) should match the whole line after the keyword States .

import re

print(re.findall(r"States\n(.*)", fp.read())[0])

Output:

91.9
