Question

I’ve been using Perl for some time and have gotten used to the syntax:

return "$var1$var2";

for easily returning a concatenation of two strings in one step. Is there a way to do something similar in Python? I’d love to avoid doing it in two steps, if possible.

Simple:

>>> "a" + "b"
'ab'
>>> "%s%s" % ("a", "b")
'ab'
>>> "{a}{b}".format(a="a", b="b")
'ab'
>>> "{}{}".format("a", "b")
'ab'
>>> "{0}{1}".format("a", "b")
'ab'
>>> "a" "b"
'ab'
>>> "".join(("a", "b"))
'ab'
