Re: [Tutor] Tutor Digest, Vol 176, Issue 13
Also, try (works for me in Python3)
rivers = {'nile' : 'egypt', 'ohio' : 'US', 'rhine' : 'germany' }
for key, value in rivers.items():
print (key)
for key, value in rivers.items():
print (value)
for key, value in rivers.items():
print ("The " + key + " is in the country of " + value)

Re: [Tutor] Help please
The program works as is in Python3. For Python2, change input to raw_input
and see if that makes it work (I know it worked for me when I had Python2).
Also, it looks better to use " + " instead of a comma:
print("Combining these foods will you," + new_food)
Also, colons and spaces are good practices when using input boxes, such as
food_1=raw_input("Sushi: ")

[Tutor] Python
I fully understand the concept of what I am trying to do and I know that you can type out the algorithms to find mean, median, and mode but I used a shortcut by import the statistics function. Which yields the same results and the program passes with a 100% in the grading software However, it does not print the expected output, but rather some random sequence of characters and numbers. I do not understand why. Do you know why? ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I'm very glad that at least one of us understands what you are trying to
do, but I have no clue what it is.

The same results as what?

Great!

Your computer is cursed? Your cat walked over the keyboard?
I don't understand how your two statements can be reconciled. You say
that the program pass the grading software. Surely that means it must
print the expected output. (How else will the grading software know it
gives the correct results?)
But then you say it prints gibberish. So I imagine you are doing this:
print(mean([1, 2, 8, 9]) # expected output is "5"
# output actually printed is "dz!gwd{7p3^)n3d%hw8"
# and the grading software says "Correct, full marks!"
which makes no sense to me.
By the way, I'm the author of the statistics module, so I'm very glad to
hear that you are using it, but if the point of the exercise is to write
your own (simple?) versions of mean, median and mode, isn't it cheating
to use the pre-written ones?

It may "look better" but be aware that they don't do
the same thing and the plus sign is a lot less efficient
computationally since it creates a new string for
each addition.
For a simple case like this it won't matter but if
you had a lot of short strings being added together
in a loop it could slow things down quite a bit.
The other problem with the plus sign is that it
requires all arguments to be strings whereas the
comma separated list gets automatically converted
to a string by Python (by calling str(x) ) so is
in general more reliable.
