Print without space in python 3

by

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
