How to read line from an input file without \n

In python, when you read each line from a file, the line string will contain \n at the end of line (1 character).
So, you have to remove it manually unlike Java you can read line in Scanner class.

f = open(...)               # Open file

f.readline().rstrip('\n')   # Remove last character
or
f.readline()[:-1]           # Remove last character
