Two Dictionaries and a Sum!
Confusing subject for a confusing problem (to a novice like me of course!)
Thx for the help in advance folks
I have (2) dictionaries:
prices = {
"banana": 4,
"apple": 2,
"orange": 1.5,
"pear": 3
}
stock = {
"banana": 6,
"apple": 0,
"orange": 32,
"pear": 15
}
Here's my instructions:
consider this as an inventory and calculate the sum (thats 4*6 = 24 bananas!)
HERES MY CODE:
for key in prices:
print prices[key]*stock[key]
HERES THE OUTPUT:
48.0
45
24
0
ISSUE:
I need to find a way to add all of those together...any pointers?

Novice Issue
Good Day all, currently writing a script that ask the user for three things;
1.Name
2.Number
3.Description
I've gotten it to do this hurah!
print "Type \"q\" or \"quit\" to quit"
while raw_input != "quit" or "q":
print ""
name = str(raw_input("Name: "))
number = str(raw_input("Number: "))
description = str(raw_input("Description: "))
but here a few things, can anyone help me on figuring out how to at the users
whim print out all of the names, numbers and descriptions. this is sort of an
information logger.
additionally, minor issue with getting script to stop when q or quit is typed
any help would be greatly appreciated

Joining this group has been the smartest decision since birth
Firstly, thanks Chris - str() [REMOVED]
and yes i would like to retain them until the end of the loop simply for
printing or viewing purposes. [I'll DO MORE RESEARCH ON LISTS]
Secondly, thanks Wolfgang
while raw_input not in ("quit", "q") - genius, i get your point clearly
Thirdly, thanks mark
went through the link you provided, insightful
Cheers

(Learner-here) Lists + Functions = headache
Hey guys and gals doing this tutorial(codecademy) and needed a bit help from the experienced. I'm writing a function that takes a list(one they supply during runtime) here's what my function is supposed to do 1. for each instance of the string "fizz" make a count 2. Finally return that count here's my code: def fizz_cout(x): count = 0 for item in x: while item == "fizz": count += 1 return count Please remember that i am a eager beginner, where am i going wrong? -- http://mail.python.org/mailman/listinfo/python-list

Thank you Alex - much appreciated, about to implement right now! -- http://mail.python.org/mailman/listinfo/python-list
