converting list of strings and getting the total as integer

I have a list of integers stored as strings and would like to convert it and get its total in integer and they print the total.

What is the easiest way to do that?

The list is as follow:

string_numbers = ['55','63','43','44']

I want to create it in a for-loop.

thanks

Using list comprehension

print(sum([int(i) for i in string_numbers]))
# 205

Using functools.reduce

from functools import reduce
print(reduce(lambda x, y: int(x) + int(y), string_numbers))
# 205

Expanded loop:

total = []
for i in string_numbers:
    total.append(int(i))
print(sum(total))

You can use the builtin functions sum and map. Map is a functional equivalent of a for loop.

>>> string_numbers = ['55','63','43','44']
>>> sum(map(int, string_numbers))
205

You can also use a generator expression instead of map.

>>> sum(int(n) for n in string_numbers)

There you go:

string_numbers = ['55','63','43','44']

total = 0
for item in string_numbers:
    total = total + int(item)

print(total)
