#We provide you with a number N.

#Create a list then, using a loop, populate the list with N elements. Set each list element to the index multiplied by 10.

#Beware: we might pass in a value 0, in which case you should return an empty list.

# Get N from the command line
import sys
N= int(sys.argv[1])

# Your code goes here
#create a list

my_list = []
my_newlist =[]
if N <= 0:
    print(my_list)

else:
    for x in range(N):
        my_list.append(x)
        my_newlist= [i* 10 for i in my_list] # not getting the statement 'i * 10 for in i' statement
    print(my_newlist)

##############
We are passing in 3 inputs.

a list of numbers
a multiplier value, M
a value, N
You should multiply every Nth element (do not multiply the 0th element) by M. So, if N is 3, you start with the 3rd element, which is index 2.

If there are less than N elements then you should output the unchanged input list.
