I stumbled into finding out that
>>> "a" "b"
'ab'
or
>>> print("a""b")
ab
Note that there is not even a space required between the two strings.
I find this is surprising to me as "a" "b" is much less readable to me
than "a" + "b" . And since Python is all about easily readable code,
why was this feature implemented? Is there a use case where it is
more desirable to not have a string concatenation operator explicitly
used? The only thing that comes to my mind are strings spread over
multiple lines, say
print("This will be a ..."
"...very long string...")
But is this preferable to
print("This will be a ..." +
"...very long string...")
? I personally prefer the latter, so I am probably missing something.
BTW, I am following through (So far!) on my New Year's resolution to
persistently work through some Python books. I've knocked off "Python
Crash Course", which I think is a fine beginner's book. Now I am
starting "Think Python, 2nd ed.", which is an intro to C.Sc.-type
book. So I imagine I may come up more questions along the lines of
today's--be forewarned!
