Python Strings not matching

I am pretty new to Python, trying to calculate some time, get two strings from different sources to be equal, but the are FALSE, when tested. First string is pulled sliced from a single line file, the other is set as a variable in the code. Both show as str, same apparent value, but when checked to be equal, they are FALSE.
from datetime import datetime
file=open("test.db","r")
for i in file:
print(i)
print(repr(i))
print(str(i.rstrip('n')))
ci_time = (str((i.rstrip('n'))[14:20]))
print(ci_time)
ci_time1 = '08:00'
print(type(ci_time))
print(ci_time)
print(type(ci_time1))
print(ci_time1)
print(ci_time == ci_time1)
file.close()
Here is my output...
$ python3 test.py
CI 2018-11-23 08:00 CO 2018-11-23 17:00
'CI 2018-11-23 08:00 CO 2018-11-23 17:00n'

So if you look carefully you will see that your ci_time variable actually has a trailing space:
ci_time
>>'08:00 '
You can remove this using:
ci_time.strip()
>>'08:00'
Or alternatively you can update the index in your string slice to be [14:19]

Thanks, I hadn't tried it from the interpreter (lesson learned). I updated the slicing, thanks for the answer.

Try adding strip() to ci_time as given below, you need to strip the space in ci_time.
print(ci_time.strip() == ci_time1)
ci = 'CI 2018-11-23 08:00 CO 2018-11-23 17:00'
print len(str(ci[14:20])) --6
print len(str(ci[14:20]).strip()) --5
