i'm new in the python world and i have small issue. im trying to run this action for example:
print ('Hello World')
print('1','2')
But i'm getting this output:
Hello World
('1','2')
Why the second row is not showing properly?
I'm using a mac laptop with python version 2.7
Thanks for the help.
Because () is used for grouping, it does not have an effect in the execution level but it makes your code look prettier:
if ( 1 > 2 > 3):
is totally samw with
if 1 > 2 > 3:
Most important part is, (1) is not a tuple with a single element. Those parenthesis are evaluated as grouper, and have no effect in execution so it is totally same with 1. On the other hand, (1,) is a tuple and , after the first element implies that.
So
print ("Hello World")
print "Hello World"
are totally the same thing. But ('1','2') is a tuple so print statement prints it.
You're trying to use the Python 3 print() function, not the Python 2 print command. However, you're trying to use this function in Python 2. Use from __future__ import print_function to get this behavior in Python 2.
See also __future__ and PEP 3105.
print ('Hello World') prints the string Hello World
print ('1','2') prints the tuple ('1','2').
( and ) with print when you're working with Python 2.x. print '1', '2' is enough.
print '1', '2' and print('1', '2') in Python 2.X? It would improve the answer.
print ('Hello World')for avoiding formatted text problems.
