Efficient way for slicing a input string and turning variables into integers or float in python
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
In urionlinejudge.com.br, a lot of their beginner problems consists in a single line input, where you slice it in different variables and put them in a formula or something.
Example, the input consists of 3 numbers in a single line, and I need to sum them all. So the input could be 10 5 6, and the output should be 21.
For now what I've been doing is the following:
var_a, var_b, var_c = input().split(' ')
var_a = int(var_a)
var_b = int(var_b)
var_c = int(var_c)
#some generic code for sum of the variables
Is there a more efficient way of doing the first part of the code?

I'm assuming you are using str.split instead of the non-existent str.slice.
For the sum, you can feed a list of strings to sum and map:
res = sum(map(int, input().split()))

efficient? I'm not sure. Prettier and Pythonic? Hell yeah.
input_str = input()
input_list = input_str.split(' ')
# And now you can iterate over this list and cast it into integers:
# list
vars = [int(i) for i in input_list]
result = sum(vars)
print(result)
