How to convert N space separated numbers into in array in Python? [closed]

Question

How do I input n integers separated by space in Python?

Suppose I want to input n elements in an array separated by space such as

3
1 2 3

In the first line we are given n and in the next line n inputs follow. How can I store them in an array?

Answer 1

Two ways:

1. using input()¹ and. This prompts the user to enter inputs:

   int_list = [int(x) for x in input("Enter integers:").split()]
   

   .split() separates the values in the input by spaces.

2. using sys.argv, you can specify input from the command line

   import sys
   int_list = [int(x) for x in sys.argv[1:]]

Answer 2

numbers = input("Enter the numbers: ") #ask for input

numbersArray = [] #array to store the input

for number in numbers:
    numbersArray.append(number) #add input to the array

Not that at this point if for example the input is 1 2 3 then the array looks like this:
['1',' ','2',' ','3'] so you have to remove the ' ' from it:

numbersArray = numbersArray[::2]

Now testing with this input 1 2 3 calling print(numbersArray); will output ['1', '2', '3'].
