when use the ()

Hi

I was wondering when I need to use () after a word. Sometimes I get the output by just typing the name and sometimes it is mandatory to put () behind it

basics.py
file_object = open('basics.txt')
data = file_object.read()

Parentheses after a function name invoke (or "call") the function, causing it to run and return a value (if that's what it is designed to do).

But to access a value stored in an ordinary variable you only need the name.
