Print new output on same line

Question

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

Solution 1

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.

Solution 2

* 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> = " "),

0 1 2 3 4 5 6 7 8 9

Solution 3

Similar to what has been suggested, you can do:

print(i, end=',')

Output: 0,1,2,3,

Solution 4

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="")

Solution 5

You can do something such as:

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

Thanks. Yes very true that print i, will have an inserted space. What would the code be for it behaving like python 2 with comma?

[DSM]

Same thing but with end = ' '. Instead of ending every print "line" with nothing, you end it with a space.

Thanks for the quick response and update. That makes so much more sense now. I read the help function a dozen times and wasn't obviously paying attention. :)

Read the question. print i, only works in python 2 not python 3.

[Avichal Badaya]

Alright, I missed it. I will edit the answer.

[onxx]

That only works in in python 2.x this post is for python 3.x print usage

This answer turned up in the low quality review queue, presumably because you don't provide any explanation of the code. If this code answers the question, consider adding adding some text explaining the code in your answer. This way, you are far more likely to get more upvotes — and help the questioner learn something new.

[Sanket Patel]

that is leaving a space. "...Guys!<space>This is...". any workaround?

what about last 3, ?

Thanks, quick and easy.

@imo Actually his code doesn't answer the question, as the question explicitly asks for Python 3.x. Code provided .. print i, ..only works in Python 2
