Why is this printing ‘None’ in the output? [duplicate]

I have defined a function as follows:

``````def lyrics():
print "The very first line"
print lyrics()
``````

However why does the output return `None`:

``````The very first line
None
``````

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use `return` statement at end of function to return value.

e.g.:

Return None value.

``````>>> def test1():
...    print "In function."
...
>>> a = test1()
In function.
>>> print a
None
>>>
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>>
``````

Use return statement

``````>>> def test():
...   return "ACV"
...
>>> print test()
ACV
>>>
>>> a = test()
>>> print a
ACV
>>>
``````

Because of double print function. I suggest you to use `return` instead of `print` inside the function definition.

``````def lyrics():
return "The very first line"
print(lyrics())
``````

OR

``````def lyrics():
print("The very first line")
lyrics()
``````
