Return statement on multiple lines

Have scoured the interwebs trying to figure this out but with no luck. As far as I know you usually only have one return statement however my problem is that I need to have line breaks in my return statement in order for the testing to return 'true'. What I've tried is throwing up errors, probably just a rookie mistake. My current function with no attempts to make a line break is below.

def game(word, con):
   return (word + str('!')
   word + str(',') + word + str(phrase1)

Are new line breaks (\n) supposed to work in return statements? It's not in my testing.

the simple code to understand

def sentence():
    return print('ankit \nkalauni is\n the\n new\n learner\n in\n programming')
sentence()

the output:
ankit
kalauni
is
the
new
learner
in
programming

easy peasy way to return the multiple lines in python

First - you're using str() to convert several strings to strings. This is not neccessary.

Second - there's nothing in your code that would insert a newline in the string you're building. Just having a newline in the middle of the string doesn't add a newline, you need to do that explicitly.

I think that what you're trying to do would be something like this:

def game(word, con):
    return (word + '!' + '\n' +
        word + ',' + word + str(phrase1))

I'm leaving in the call to str(phrase1) since I don't know what phrase1 is - if it's already a string, or has a .__str__() method this shouldn't be needed.

I'm assuming that the string you're trying to build spans the two lines, so I've added the missing parenthesis at the end.

You can split up a line in a return statement, but you have forgotten a parenthesis at the end and that you also need to separate it with another operator (in this case, a +)

Change:

def game(word, con):
   return (word + str('!')
   word + str(',') + word + str(phrase1)

To:

def game(word, con):
   return (word + str('!') + # <--- plus sign
   word + str(',') + word + str(phrase1))
#                                       ^ Note the extra parenthesis

Note that calling str() on '!' and ',' is pointless. They are already strings.

In python, an open paren causes subsequent lines to be considered a part of the same line until a close paren.

So you can do:

def game(word, con):
    return (word + str('!') +
            word + str(',') +
            word + str(phrase1))

But I wouldn't recommend that in this particular case. I mention it since it's syntactically valid and you might use it elsewhere.

Another thing you can do is use the backslash:

def game(word, con):
    return word + '!' + \
           word + ',' + \
           word + str(phrase)
    # Removed the redundant str('!'), since '!' is a string literal we don't need to convert it

Or, in this particular case, my advice would be to use a formatted string.

def game(word, con):
    return "{word}!{word},{word}{phrase1}".format(
        word=word, phrase1=phrase1")

That looks like it's functionally equivalent to what you're doing in yours but I can't really know. The latter is what I'd do in this case though.

If you want a line break in the STRING, then you can use "\n" as a string literal wherever you need it.

def break_line():
    return "line\nbreak"
