I'm working on Exercise 4 from Part 4 from Learning
Python. I'm trying to write a function using **args.
I want to create a function that adds its arguments
together. Here is what I have written:
def adder(**args):
for x in args.keys():
print x
print adder()
print "---"
print adder(a=5)
print "---"
print adder(a=5,b=6)
print "---"
print adder(a=5,b=6,c=7)
print "---"
print adder(ugly=7, good=6, bad=5)
print "---"
Here is my output:
None
---
a
None
---
a
b
None
---
a
c
b
None
---
ugly
bad
good
None
---
Where do the None objects come from?
