Syntax error when trying to create new empty list in Python

I'm embarking on my Project Euler adventure and the first line of my Python code is tripping me up. The error I get for the code below is: Traceback (most recent call last): File "python", line 3 3multlist = [] ^ SyntaxError: invalid syntax

Which makes NO sense because I've verified up and down that the line in question does have proper syntax!

Code below:

3multlist = []
5multlist = []

3starter = 0
5starter = 0

While (3starter < 1000):

    3starter = 3starter + 3
    3multlist.append(3starter)

While (5starter < 1000):
    5starter = 5starter + 3
    5multlist.append(5starter)

b = sum(3multlist)
c = sum(5multlist)
d = b + c

print d

This is because variable name can not start with a numeral.Below are the variable naming convention rules Variables names must start with a letter or an underscore, such as: _

  • underscore
  • underscore_

The remainder of your variable name may consist of letters, numbers and underscores.

  • password1
  • n00b
  • un_der_scores

Names are case sensitive. case_sensitive, CASE_SENSITIVE, and Case_Sensitive are each a different variable

Correct version of your program would be

multlist = []
multlist = []
starter = 0
starter = 0

while (starter < 1000):

    starter = starter + 3
    multlist.append(starter)

while (starter < 1000):
    starter = starter + 3
    multlist.append(starter)
b = sum(multlist)
c = sum(multlist)
d = b + c

print(d)

If you are using python 3 you need to use brackets with print statement else you can drop them.

It looks like python does not like the number in front of the list declaration

try multlist3 rather than 3multlist
