Why does print() print outputs one below the other and not the other?

Continuing my studies in Python, a new doubt arose. Before asking, I researched here on Sopt using the expression "print next to Python" and I did not find anything that could kill my doubt and solve the problem. So come on:

I wrote the following code, very simple, just to illustrate the problem, let’s go to it:

a = int(input("Digite o primeiro número: "))
b = int(input("Digite o segundo número: "))
for i in range(a+1,b):
    print(i)

I got the next exit:

Digite o primeiro número: 5
Digite o segundo número: 20
6
7
8
9
10
11
12
13
14
15
16
17
18
19
>>>

The doubt is as follows: Why the function print() always prints the outputs this way, one underneath the other? How to make it print the outputs next to each other without using list resources?

You can do this way using the Python 2

print "Seu texto",

And in this way using the Python 3

print("Seu texto", end="", flush=True)

The function print has a final parameter whose default is "n". Set you up a string empty prevents it from creating a new line in the final.

  • It worked, but then the exit got all the numbers glued together, like it was a big multi-digit number. However, a change in what you posted made it work. I did so: print(i,end=",",flush=True).

    That, the end swaps the pattern ' n' which is the line break for "" which is an empty string, so by putting "," it swaps ' n' for comma or any other string you want :)

The print() is a function Buil-in of Python which has some arguments defined by default, let’s see:

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

We can alternate the argument end if we wish to make a print differentiated, as for example:

print(i, end=' ')

We will have as a result:

output: 6 7 8 9 10 11 12 13 14 15 16 17 18 19

The signature of the function print is the following:

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

The third parameter, end, is what python will put after its string (line break by default). You can override it the will.

a = int(input("Digite o primeiro número: "))
b = int(input("Digite o segundo número: "))
for i in range(a+1,b):
    print(i, end=' ')

Digite o primeiro número: 5
Digite o segundo número: 20
6 7 8 9 10 11 12 13 14 15 16 17 18 19

  • Yes, I tested with a comma and with empty spaces, it worked. What would be the parameter flush?
