Given a list of integers, return the sum of only the odd numbers in the list. If the list is empty, return 0.

NOTE: To read the input list in Python, you can, for example, use the command lis=eval(input()) which stores the input list in the variable lis. To write the list to output you can, for example, use the print command followed by the name of the result list.
