[spyder] how to print a list on one horizontal line, in python 3

[Lei]

Hi experts,

I am using python 3.

I wrote in IPython console in Spyder

for elem in [10, 20, 25, 27, 28.5]:

print(elem),


But the results are


10

20

25

27

28.5

As I learned, the comma in the syntax "print(elem)," will prevent the use
of newline character. Why does it not work here?

How can I make the results in one line? Like


10 20 25 27 28.5


I know I can use

print([elem for elem in [10, 20, 25, 27, 28.5]])

and I get
[10, 20, 25, 27, 28.5]

But this is not something I want. What I want is, with the first codes, why
the results are in vertical line, even with the comma?

Thanks!

Hello Lei,

As I learned, the comma in the syntax "print(elem)," will prevent the use of
newline character. Why does it not work here?

This method of suppressing the newline is outdated. It was used with the
print statement in python2, but in python3 print is a function, so the comma
does not work anymore.

How can I make the results in one line?

You can do almost the same thing you tried to do

for elem in [10, 20, 25, 27, 28.5]:
print(elem, end=" ")

or just use the tuple unpacking when calling print

print(*[10, 20, 25, 27, 28.5])

Thank you very much!

That works in Python 2:

In [1]: for elem in [10, 20, 25, 27, 28.5]:
...: print(elem),
...:
10 20 25 27 28.5

but not using the print function from Python3:

In [3]: from __future__ import print_function

In [4]: for elem in [10, 20, 25, 27, 28.5]:
print(elem),
...:
10
20
25
27
28.5

To get it to work do:

In [5]: for elem in [10, 20, 25, 27, 28.5]:
print(elem, end=',')
...:
10,20,25,27,28.5,
