def sillycase(g):
v = len(g)
p = v/2
p = round(p)
for i in range(len(g)):
if i < p:
print(g[i].lower())
else:
print(g[i].upper())
sillycase("Treehouse")
This was right from my interpreter but treehouse says it isn't in the python collections last question

a single string that is the case-adjusted version of the input.
How would you store the first half of the word as lower(), and the trailing half as upper(), then join the two and return the value?
Hint: you can lowercase to a portion of a word using: first_half = g[:p].lower()

v = len(g)
p = v/2
p = round(p)
first = g[:p].lower()
second = g[p:].upper()
print(first+second)
sillycase("Treehouse")
in my interpreter it returns kennEth which is correct
but treehouses interpreter returns Error: our function didn't return the right output. Got 'None', expected 'kennETH'.

Treehouse Moderator 68,441 PointsThe reason the code challenge got 'None' is because your function does not have a return
statement. Change the print(first+second)
to return first+second
Thomas Katalenas
11,033 PointsThat still doesn't explain why None was coming, because print worked fine in my interpreter

Treehouse Moderator 68,441 PointsAll statements return something. When a function is called that does not have an explicit return
statement, a return None
is implied. So your sillycase()
function may be printing but the grader is looking at the return value and seeing this default 'None' being returned. The grader does not look at what would be the console output. It instead looks the output of the executed test statements.
Try this in your console:
result = sillycase('Kenneth')
print(result)
The value of result
is what the grader checks

if
statement.
