I want the greet function to say "Hi Sam, Hi Cody" using the format function but I am getting this error:
greet(names())
TypeError: greet() missing 1 required positional argument: 'y'
def names():
def name1():
x = "Sam"
return x
def name2():
y = "Cody"
return y
What do I need to put in greet(names()) to get this to work?
from names import names
def greet(x,y):
template = "Hi {}, Hi {} ".format(x,y)
print(template)
greet(names())
Is this what you're after:
def name1():
return 'Sam'
def name2():
return 'Cody'
def greet (x, y):
print (f'Hi {x}, Hi {y}')
greet (name1(), name2())
# Result:
# Hi Sam, Hi Cody
names() returning multiple outputs
If you wanted to write a single function names()
that returns multiple outputs, you can do it like this:
def names():
return 'Sam', 'Cody'
The return from names()
is a tuple
containing two strings. If you pass it directly to greet()
, you'll be passing greet()
a single argument - a tuple
that happens to contain two things within it. That will produce the error you were getting:
greet (names())
TypeError: greet() missing 1 required positional argument: 'y'
You could, on the other hand, unpack the tuple
returned by names()
when you pass it to greet()
, like so:
greet (*names())
# Result:
# Hi Sam, Hi Cody
