python - 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.

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.

* for python 2.x *

Use a trailing comma to avoid a newline.

print "Hey Guys!",
print "This is how we print on the same line."

The output for the above code snippet would be,

Hey Guys! This is how we print on the same line.

* for python 3.x *

for i in range(10):
    print(i, end="<separator>") # <separator> = \n, <space> etc.

The output for the above code snippet would be (when <separator> = " "),

Similar to what has been suggested, you can do:

print(i, end=',')

Output: 0,1,2,3,

print("single",end=" ")
print("line")

this will give output

single line

for the question asked use

i = 0 
while i <10:
     i += 1 
     print (i,end="")

You can do something such as:

>>> print(''.join(map(str,range(1,11))))
12345678910

>>> for i in range(1, 11):
...     print(i, end=' ')
...     if i==len(range(1, 11)): print()
... 
1 2 3 4 5 6 7 8 9 10 
>>>

This is how to do it so that the printing does not run behind the prompt on the next line.

Lets take an example where you want to print numbers from 0 to n in the same line. You can do this with the help of following code.

n=int(raw_input())
i=0
while(i<n):
    print i,
    i = i+1

At input, n = 5

Output : 0 1 2 3 4
