Get your newlines straight

Computer Science Level 2

C code snippet : 

1
 
printf("\n");

Python code snippet : 

1
 
print('\n') #can also be "\n", it makes no difference

Let the number of newlines printed by the first code snippet (C) be a a and that printed by the second code snippet (Python) be b b .

What's the value of ( a + b ) (a+b) ?

Inspired while browsing 4chan's /sci/ board.


The answer is 3.

In C/C++ 

1
 
printf("\n");

will print 1 newline, a= 1 \boxed{1}

In Python 

1
 
print('\n')

will print 2 newlines, b= 2 \boxed{2}

a + b = 3 \huge a+b=3

Yup, that's the intended solution. +1 :)

Python's print() function prints a newline by default after printing the stuff that's intended to be printed using it, which makes print('\n') print an additional newline after the intended newline is printed.

To override this, one would generally use the end parameter of print() in py3. However, for the purpose of printing a single newline, print('') works quite well.

Actually, for the purpose of printing a single new line in py3, print() works too.
