python - Printing an int list in a single line python3

Question

I'm new to python and I'm trying to scan multiple numbers separated by spaces (let's assume '1 2 3' as an example) in a single line and add it to a list of int. I did it by using:

#gets the string 
string = input('Input numbers: ') 
#converts the string into an array of int, excluding the whitespaces
array = [int(s) for s in string.split()] 

Apparently it works, since when I type in '1 2 3' and do a print(array) the output is:

[1, 2, 3]

But I want to print it in a single line without the brackets, and with a space in between the numbers, like this:

1 2 3

I've tried doing:

for i in array:
    print(array[i], end=" ")

But I get an error:

2 3 Traceback (most recent call last):

print(array[i], end=" ")

IndexError: list index out of range

How can I print the list of ints (assuming my first two lines of code are right) in a single line, and without the brackets and commas?

Answer 1

Yes that is possible in Python 3, just use * before the variable like:

print(*list)

This will print the list separated by spaces.

(where * is the unpacking operator that turns a list into positional arguments, print(*[1,2,3]) is the same as print(1,2,3), see also What does the star operator mean, in a function call?)
