How to get rid of the single quotation marks in a list inside a list?-CodePudding

I wrote this piece of code, in which I ask the user to input numbers twice, and then it joins them together in a list, inside a list. It works...buts it's in the wrong format.

Here's what I did

list=[]
for i in range(2):
    userinput = input("Enter some numbers: ")
    x = userinput.split()
    list.append(x)
print(list)

The output is this

Enter some numbers: 1 2
Enter some numbers: 3 4
[['1', '2'], ['3', '4']]

...but I need it to be formatted [[1, 2], [3, 4]] I'm very new python, and I feel like Ive exhausted all my options, I couldnt find anything online that works (tried the join, replace etc.) , unless its impossible with my code, please help

CodePudding user response：

Use x = [int(i) for i in userinput.split()]; you have to convert the input strings to integers.

CodePudding user response：

You'll need to convert each value to an int to avoid the quotes (the values entered by the end user are strings):

list=[]
for i in range(2):
    userinput = input("Enter some numbers: ")
    x = userinput.split()
    list.append([int(v) for v in x])
print(list)

Output:

Enter some numbers: 3 2 1 
Enter some numbers: 4 5 6
[[3, 2, 1], [4, 5, 6]]

CodePudding user response：

You can do it in one line like below :

input_list = [int(input("Enter some numbers: ")) for i in range(2)]
