List sum (with string types) in Python

Michael Zippo 18.07.2021

Examples:

 Input: list1 = [12, ’geek’, 2,’ 41’, ’for’, 10,’ 8’, 6, 4, ’geeks’, 7,’ 10’] Output: 100 Input: list1 = [100, ’geek’, 200,’ 400’, ’for’, 101,’ 2018’, 64, 74, ’geeks’, 27,’ 7810’] Output: 10794

For this we use

# Python program for finding the sum of a list with different
# types.

def calsum (l):

# return the sum of the list using a list comprehension

< / code> return sum ([ int (i) for i in l if type (i) = = int or i.isdigit ()])

    
  # List declaration  
   list1   =   [  12  ,   ’geek’  ,   2  ,   ’41’  ,   ’for’  ,   10  ,   ’8’  ,   6  ,   4  ,  ’ geeks’  ,   7  ,   ’10’  ] 
   list2   =   [  100  ,   ’geek’  ,   200  ,   ’400’  ,  ’ for’  ,   101  ,   ’2018’  ,   64  ,   74  ,   ’geeks’  ,   27  ,  ’ 7810’  ] 
   
  # Result of the list sum  
   print   calsum (list1) 
   print   calsum (list2)
