Python: how to add spaces between strings

Question

To be more specific, I'm trying to print several results of a function in the form of a sentence like so print str(function(first)) + str(function(second)) + str(function(third)) and so on, but I've come across the problem that there are no spaces between the individual strings.

So, what I want to know is how I add spaces between each of those strings.

use join()

print " ".join([str(function(first)), str(function(second)), str(function(third))])

You can also pass join a generator expression rather than a list, if that's more convenient: " ".join(str(function(x)) for x in [first, second, third])

Alternatively, " ".join(map(lambda x: str(function(x)), (first, second, third)))

Since i'm new to join(), what advantages/disadvantages does it have when compared to just doing print function(first), function(second), etc.

It is faster. With '+' operator you create new string with each concatenation. str.join is optimized, so there is less memory allocation and deallocation. Also it is more 'pythonic'. You want do just that - join results of your functions in one sentence, right?

print function(first), function(second), function(third)

or use string formatting:

print '{0} {1} {2}'.format(function(first), function(second), function(third))
