Sum function prob TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’

by

input takes a input as string

>>> numbers = input("Enter your numbers followed by commas: ")
Enter your numbers followed by commas: 1,2,5,8
>>> sum(map(int,numbers.split(',')))
16

you are telling user to give input saperated by comma, so you need to split the string with comma, then convert them to int then sum it

demo:

>>> numbers = input("Enter your numbers followed by commas: ")
Enter your numbers followed by commas: 1,3,5,6
>>> numbers
'1,3,5,6'   # you can see its string
# you need to split it
>>> numbers = numbers.split(',')
>>> numbers
['1', '3', '5', '6']
# now you need to convert each element to integer
>>> numbers = [ x for x in map(int,numbers) ]
or
# if you are confused with map function use this:
>>> numbers  = [ int(x) for x in numbers ]
>>> numbers
[1, 3, 5, 6]
#now you can use sum function
>>>sum(numbers)
15
