I understood this video but once i added a print function to show the values it also returns None. I don't know why.

code: def my_function(arg1, arg2, arg3, arg4): print(arg1) print(arg2) print(arg3) print(arg4)

my_function("Hello", "I", "love", "python")

packing example

def packer(*pkr): print(pkr) for val in pkr: print (val)

print(packer("Hello", "I", "love", "python"))

The return shows both ways to run this function but the last line returns None as well. I would like to figure out why that print function is returning both the tuple and None. It works perfect if i remove the print function as follows:

packer("Hello", "I", "love", "python")

To print the result of calling a function, the function must return something. So since these functions print internally but don't return any value, their value will be "None".

Have the function return a value instead of (or in addition to) printing and then you'll see that value as the output.
