Basic for loop in Python 3

Question

I'm a beginner to Python and I'm having some trouble with this. I have to make a for loop out of this problem. Can anyone explain how I would go about this?

nextNValues (startValue, increment, numberOfValues)

This function creates a string of numberOfValues values, starting with startValue and counting by increment. For example, nextNValues (5, 4, 3) would generate a string of (not including the comments):

5 - the start value
9 - counting by 4, the increment
13 - stopping after 3 lines of output, the numberOfValues

You could use range(startValue,startValue+(increment*numberofValues),increment) — Srinivas Reddy Thatiparthy

Do you want a string? Or do you want to print the numbers to the console? Or do you want a list of numbers? — jayhendren

I can't use a print statement inside the function. So I have to use a return statement and then create a "main" function where I would print the output. this is what I got so far: — user2813310

def nextNValues (startValue, increment, numberOfValues): result = 0 for i in range (numberOfValues): result = startValue + i * increment return increment — user2813310

+1 also you can use xrange and produce a generator (where the sequence is generates as each next element is accessed instead of all at once like this (this is good if you want a LONG sequence)

there is no xrange in python3.range=xrange in python3. :)

for i in range(numberOfValues):
    print startValue + i * increment

I am not sure if that is exactly what you are looking for... but it is my suggestion based on the information you have posted.

It would probably be easiest to write a for loop with an index like i and use that to add i*increment ti start value and save the resulting value to a list. Have the loop run numberOfValues times. If this is homework it would be better for you to write out the actual code for yourself
