Python Question

Print new output on same line

I want to print the looped output to the screen on the same line.

How do I this in the simplest way for Python 3.x

I know this question has been asked for Python 2.7 by using a comma at the end of the line i.e. print I, but I can't find a solution for Python 3.x.

i = 0
while i <10:
i += 1
## print (i) # python 2.7 would be print i,
print (i) # python 2.7 would be 'print i,'


Screen output.

1
2
3
4
5
6
7
8
9
10





What I want to print is:

12345678910

From help(print):

Help on built-in function print in module builtins:

print(...)
    print(value, ..., sep=' ', end='\n', file=sys.stdout)

    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file: a file-like object (stream); defaults to the current sys.stdout.
    sep:  string inserted between values, default a space.
    end:  string appended after the last value, default a newline.

You can use the end keyword:

>>> for i in range(1, 11):
...     print(i, end='')
... 
12345678910>>> 

Note that you'll have to print() the final newline yourself. BTW, you won't get "12345678910" in Python 2 with the trailing comma, you'll get 1 2 3 4 5 6 7 8 9 10 instead.
