I wonder why there’s “None” after all those.

Don’t use print function, only use function sing_song(). Function print is in sing_song(), so you don’t need call it again.
I think function print in You’r example, is try to find argument’s or conditions for both sing_song(), and print can’t find it.
I’m only beginer, if i’m wrong, please correct me.

Why does this exercise have print(sing_song) typed out in it already, if we’re not supposed to use print()? Is that a glitch in the exercise?
The instruction does not say, call print(sing_song()) , it says call(sing_song())
can I just insert a variable inside of the function like this:
def welcome_song():
song=""“Welcome to Engrossing Grocer’s.
Our special is mandarin oranges.
Have fun shopping!”""
print(song)
welcome_song()
I don’t see anything wrong with this:
def sing_song():
print(“You may say I’m a dreamer”)
print(“But I’m not the only one”)
print(“I hope some day you’ll join us”)
print(“And the world will be as one”)
call sing_song() below:
print(sing_song()),print(sing_song())
Here’s the output:
You may say I’m a dreamer
But I’m not the only one
I hope some day you’ll join us
And the world will be as one
None
You may say I’m a dreamer
But I’m not the only one
I hope some day you’ll join us
And the world will be as one
None
I figured it out. Don’t call print as it is already in the function.
I think it should be listed as below
print(sing_song())
this line of code means the sing_song() function will be called out every time you are trying to call it out.
"print" function is actually a “functional” button to the command. To run the function, we have to use the button to call it out.
so “print(sing_song())” is good enough for the question.
for me it says call sing_song() below
Earlier we learnt that we can also declare a variable and use triple quotes at start and end to print multi-line of strings.
What is the difference between using the multi-line of strings by using triple quotes and function?
The code below returns no errors or unwanted output. You simply have to make sure you’re calling sing_song() outside of the function which you can do by making sure sing_song() is NOT indented or has any spaces then right below it calling it again.
def sing_song():
print("You may say I'm a dreamer")
print("But I'm not the only one")
print("I hope some day you'll join us")
print("And the world will be as one")
# call sing_song() below:
sing_song()
sing_song()
In this exercise, script.py introduced def without any explanation to its purpose. The introductory paragraph explains how to call a function but it did not got into details on how to create a function.
def sing_song():
print(“You may say I’m a dreamer”)
print(“But I’m not the only one”)
print(“I hope some day you’ll join us”)
print(“And the world will be as one”)
Is this keyword that we must always use with a function? Thank you.
Looks like this is explained in the next page Sorry!
