How do I take the average (mean) of inputted numbers in Python?-CodePudding

I would like to take create a code that takes an input of numbers, and then takes the average (mean) of these numbers. So far, I have this:

from statistics import mean

numbers=int(input("Enter some numbers. Seperate each number by a space: ") 
average=mean(grades)
print(average)

Running this code gives me an error stating "invalid literal for int() with base 10: ' 12 13 14 15 16 17 17'". I have tried to convert the input into a list, but this also failed; I don't know what else to do or try.

Your'e trying to convert the whole input to one int. Get the input string then split it and convert to ints individually.

from statistics import mean

user_input = input("Enter some numbers. Seperate each number by a space: ").strip()

numbers = [int(x) for x in user_input.split(' ')]

average = mean(numbers)

print(average)

CodePudding user response：

numbers=[int(x) for x in input("Enter some numbers. Seperate each 
number by a space: ").split()]
print(numbers)
average=mean(numbers)
print(average)

The idea to convert input into a list was right. Here is one of the ways to do so:

numbers = list(map(int, input().split(" ")))
average = mean(grades)
print(average)

CodePudding user response：

from statistics import mean

numbers = input("Enter some numbers. Separate each number by a space: ")

# After the input numbers is a string that looks like this "1 2 3 4"

# .split(" ") splits the string based on the space. It returns a list of individual items
# strip removes the trailing and leading white spaces
# map applies the first arg (here int) on each element of the second arg (here a list of numbers as strings)
numbers = list(map(int, numbers.strip().split(" ")))

average = mean(numbers)
print(average)
