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!
