Print without space in python 3

Question

I'm new to Python, and I'm wondering how to print multiple values without having the extra space added in between. I want the output ab rather than a b without having to call print twice:

print("a", end="") print("b") 

Also, I have the following code:

a = 42 b = 84  

and I want to print their values as a = 42, b = 84, yet if I do

print("a = ", a, ", ", b = ", b) 

extra spaces are added (it outputs a = 42 , b = 84)

Whereas the Java style,

print("a = " + a + ", b = " + b) 

raises a TypeError.

Answer 1

You can use the sep parameter to get rid of the spaces:

>>> print("a","b","c") a b c >>> print("a","b","c",sep="") abc 

I don't know what you mean by "Java style"; in Python you can't add strings to (say) integers that way, although if a and b are strings it'll work. You have several other options, of course:

>>> print("a = ", a, ", b = ", b, sep="")  a = 2, b = 3 >>> print("a = " + str(a) + ", b = " + str(b)) a = 2, b = 3 >>> print("a = {}, b = {}".format(a,b)) a = 2, b = 3 >>> print(f"a = {a}, b = {b}") a = 2, b = 3 

The last one requires Python 3.6 or later. For earlier versions, you can simulate the same effect (although I don't recommend this in general, it comes in handy sometimes and there's no point pretending otherwise):

>>> print("a = {a}, b = {b}".format(**locals())) a = 2, b = 3 >>> print("b = {b}, a = {a}".format(**locals())) b = 3, a = 2 

Answer 2

The actual syntax of the print() function is

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False) 

You can see it has an arg sep with default value ' '. That's why space gets inserted in between.

print("United","States")            #Output: United States print("United","States",sep="")     #Output: UnitedStates
