How to sum list elements in a loop?-CodePudding

How do you sum elements from lists that you have created with loops and are initially not visible?

If you say you create n` times lists and you will sum the elements in the first column, second column and so on.

x=int(input("") 
lst[]

for i in range(x):
    loop= input("")
    lst.append(loop)

CodePudding user response：

could just use the built-in function sum, that will sum all the values from the list lst, could:

x=int(input("range >>") #user inputs the range 
lst = [] #list is created

for i in range(x):
    loop= int(input("Number >>")) #creates a number that will insert in the list 'lst'
    lst.append(loop) #appending the value
print("sum:",sum(lst))

Output:

range >>3
Number >>4
Number >>4
Number >>4
sum:12

CodePudding user response：

A compact way would be:

print(sum(int(input('enter number: ')) for _ in range(int(input('enter x: ')))))

CodePudding user response：

you can use list generator to convert them to int, and then use sum function:

s = sum([int(i) for i in lst])
