Python “for i in” + variable

Question

I have the following code:

 #Euler Problem 1

    print \"We are going to solve Project Euler\'s Problem #1\"

    euler_number = input(\'What number do you want         


        

Answer 1

In Python, a for loop loops using a series of values. These can be, for example, items in a list; or these can be values that come from an "iterator".

for i in 3 makes no sense in Python, as 3 is not a series of values.

Have fun learning Python, it's a great language. Also, the Project Euler challenges are fun, so stick with them, and don't give up!

Answer 3

You probably want this:

for i in range(1, euler_number + 1):
