Process multiple input values in Python

Question

Hi so I\'m very very new to programming so please forgive me if I\'m not able to ask with the correct jargon, but I\'m writing a simple program for an assignment in which I\'m t

Sure! You'll have to provide some sort of "marker" for when you're done, though. How about this:

if num == '1':
    lst_of_nums = []
    while True: # infinite loops are good for "do this until I say not to" things
        new_num = raw_input("Enter value: ")
        if not new_num.isdigit():
            break
            # if the input is anything other than a number, break out of the loop
            # this allows for things like the empty string as well as "END" etc
        else:
            lst_of_nums.append(float(new_num))
            # otherwise, add it to the list.
    results = []
    for num in lst_of_nums:
        results.append(num/1e4)
    # this is more tersely communicated as:
    #   results = [num/1e4 for num in lst_of_nums]
    # but list comprehensions may still be beyond you.

If you're trying to enter a bunch of comma-separated values, try:

numbers_in = raw_input("Enter values, separated by commas\n>> ")
results = [float(num)/1e4 for num in numbers_in.split(',')]

Hell if you wanted to list both, construct a dictionary!

numbers_in = raw_input("Enter values, separated by commas\n>> ")
results = {float(num):float(num)/1e4 for num in numbers_in.split(',')}
for CGS,SI in results.items():
    print "%.5f = %.5fT" % (CGS, SI)
    # replaced in later versions of python with:
    #   print("{} = {}T".format(CGS,SI))
