Re: Python-Help ( Mean,Median & Mode)

[Alfred Canoy]

Hello,
I revised my source code. It was doing great but I'm having problem listing 
all the numbers that I'd input. How can I input all the numbers that I 
selected? The source code and the output below:

                                       Source code:
# compute the Mean, Median & Mode of a list of numbers:
sum = 0.0
print 'This program will take several numbers then average them'
count = input(' How many numbers would you like to sum: ')
current_count = 0
freq = {}
freq [current_count] = number
while current_count < count:
   current_count = current_count + 1
   number = input ('Enter a number: ')
   print "Number", current_count,":",number
   sum = sum + number
print ' The average is:', sum/count
# list the numbers selected by user then gets the median & mode
listNumbers=[]
for list in number:
   listNumbers[list]=listNumbers.get(x,0)+1
print listNumbers
freq = {}
current_count(freq)=number
while number != 0:
   number = input ('Enter a number: ')
   count = count + 1
   sum = sum + number
   try:
       freq[number] += 1
   except KeyError:
       freq[number] = 1
max = 0
mode = None
for k, v in freq.iteritems():
   if v > max:
       max = v
       mode = k
print mode
                                           Output:
This program will take several numbers then average them
Number 1 : 6
Number 2 : 9
Number 3 : 8
Number 4 : 4
Number 5 : 2
The average is: 5.8
Traceback (most recent call last):
 File 
"C:\Python24\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", 
line 310, in RunScript
   exec codeObject in __main__.__dict__
 File "A:\SLP5.py", line 23, in ?
   for x in number:
TypeError: iteration over non-sequence

Thank you much!

Hello,
I'm just new to programming and would like to ask for help..
Build a module that contains three functions that do the following:
     a.. Compute the average of a list of numbers
     b.. Finds the statistical median value of a list of numbers
The middle value in a distribution, above and below which lie an equal 
number of values.

     c.. Finds the mode of a list of numbers
The value or item occurring most frequently in a series of observations or 
statistical data.

Can you please give me clue how I should start solving the following 
problem
below? Here's the source code that I did so far:

# compute the average of a list of numbers:
# Keeps asking for numbers until 0 is entered
# Prints the average value
count = 0
sum = 0
number = 1
print 'Enter 0 to exit the loop'
while number != 0:
   number = input ('Enter a number: ')
   count = count + 1
   sum = sum + number
count = count -1
print ' The average is:', sum/count
Great start. In addition append each numbers to a list. Then it is easy to 
find the middle of the list for the median. Use a dictionary keyed by the 
numbers to count their frequency, then find the entry with the highest 
frequency.

See http://www.honors.montana.edu/~jjc/easytut/easytut/ for lists and 
dictionaries.

Give it a shot, show us what you come up with, and we'll take the next 
step.
