Is it possible to print text on the same line in Python?
For instance, instead of having
1
2
3
I would have
1 2 3
Thanks in advance!

Assuming this is Python 2...
print '1',
print '2',
print '3'
Will output...
1 2 3
The comma (,) tells Python to not print a new line.
Otherwise, if this is Python 3, use the end argument in the print function.
for i in (1, 2, 3):
print(str(i), end=' ') # change end from '\n' (newline) to a space.
Will output...
1 2 3

Removing the newline character from print function.
Because the print function automatically adds a newline character to the string that is passed, you would need to remove it by using the "end=" at the end of a string.
SAMPLE BELOW:
print('Hello')
print('World')
Result below.
Hello
World
SAMPLE Of "end=" being used to remove the "newline" character.
print('Hello', end= ' ')
print('World')
Result below.
Hello World
By adding the ' ' two single quotation marks you create the space between the two words, Hello and World, (Hello' 'World') - I believe this is called a "blank string".

when putting a separator (comma) your problem is easily fixed. But obviously I'm over four years too late.
print(1, 2, 3)

Print a list of space-separated elements

Hi: I am new to python and programing.
I have a silly question that I couldn't solve.
a=[1,2,3,4,5]
for i in a:
print(i,end=' ')
will get a out put:
1 2 3 4 5
There are space between each numbers in the system out print: ( s means space)
1s2s3s4s5s
How can I remove the last space? The correct out put will be :
1s2s3s4s5
a=[1,2,3,4,5]
print(' '.join([str(x) for x in a])
This will first convert each element of 'a' to string and then join all element using join(). It must be noted that ' ' can be replaced with any other symbol as well
There are various ways, but a simple way is join:
print(' '.join(a), end='')
You can also directly use print:
print(*a, sep=' ', end='')

I just started python few days ago, and didn't really understand end =' ' in nested loop. Can anybody explain me this
count=0
for i in range(10):
for j in range(0, i):
print (count, end='')
count +=1
print()
'' is the "empty string" (e.g. nothing). The "end" parameter is what gets printed after the preceding set of variables. The default value of "end" is the newline (i.e. subsequent print statements will begin on a new line). By specifying '', the loop above will literally print out
1
22
333
4444
55555
666666
7777777
88888888
999999999
with each inner loop result on a single line. Without the end='' param, it would get printed out as:
1
2
2
3
3
3
...
9
9
The final print() at the end of the inner loop, just prints a new line.
End is print function keyword argument. The default value of end is \n meaning that after the print statement it will print a new line. If you redefine end, print will output your redefined value after using.
print("123", end="=")
#prints '123='
'' means empty string, so, you wil get output with no delimiters.
The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed,
prints an according Count value and stays in the same line. If you left out the end='' each time a newline would be printed
We learn everything by doing, So lets suppose we remove that end="" at the end of the print function. So you code will look like this
count=0
for i in range(10):
for j in range(0, i):
print (count)
count +=1
print()
and the output will be as
1
2
2
3
3
3
...
Now this output may or may not be your desired output depending on where you want to use the code
you may be wondering why this happens when you have not specified python to add a new line, its due to the fact that print function add new line character at the end of the output by default so if you doesnot want that to happen add end="" for the output line end with a empty string or nothing. likewise use end="/t" for tab end="." to end the print statement with a period and so on.
ProTip
use
print()
when ever you want a new line in or out of a loop

I am trying to print some list containing '\t' and '\n' . But as python is not printing it because it is thinking it as a special character [duplicate]

I have a delim list . Now I want to print every element in delim list. But print funtion in python is printing everything except character like '\t' , '\n'. I know it is usual . But can I print this like normal characters or strings.
delim=['\t','\n',',',';','(',')','{','}','[',']','#','<','>']
for c in delim:
print c
It is giving output :
it is printing all the list skipping \t and \n
Change them to raw string literals by prefixing a r:
>>> print '\n'
>>> print r'\n'
\n
For your example this would mean:
delim=[r'\t',r'\n',',',';','(',')','{','}','[',']','#','<','>']
for c in delim:
print c
If you just want to print them differently use repr
for c in delim:
print repr(c)
Note: You will also see additional ' at the beginning and end of each string.

I want to print some text beside another text that has been printed before in python
for example
print("Hello")
a="This is a test"
print(a)
What I mean is to print like this "HelloThis is a test" not in next line I know I shoud use print("Hello",a) but I wanted to use seprated print commands!!!!
Use end='' in the first print call:
print("Hello", end='')
a = "This is a test"
print(a)
#HelloThis is a test
Help on 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.
If you are using python 2.7 (python tag on question) you can place a comma after the print to not return a new line.
print("hello"),
print("world")
Will print "helloworld" all one one line.
So in your case it will be:
print("Hello"),
print(a)
Or if your using python 3 (python3.x tag on question) use:
print("hello", end='')
print('world')
So in your case it will be:
print("Hello", end='')
print(a)

How can I suppress the newline after a print statement? [duplicate]

I read that to suppress the newline after a print statement you can put a comma after the text. The example here looks like Python 2. How can it be done in Python 3?
For example:
for item in [1,2,3,4]:
print(item, " ")
What needs to change so that it prints them on the same line?
The question asks: "How can it be done in Python 3?"
Use this construct with Python 3.x:
for item in [1,2,3,4]:
print(item, " ", end="")
This will generate:
1 2 3 4
See this Python doc for more information:
Old: print x, # Trailing comma suppresses newline
New: print(x, end=" ") # Appends a space instead of a newline
--
Aside:
in addition, the print() function also offers the sep parameter that lets one specify how individual items to be printed should be separated. E.g.,
In [21]: print('this','is', 'a', 'test') # default single space between items
this is a test
In [22]: print('this','is', 'a', 'test', sep="") # no spaces between items
thisisatest
In [22]: print('this','is', 'a', 'test', sep="--*--") # user specified separation
this--*--is--*--a--*--test
Code for Python 3.6.1
print("This first text and " , end="")
print("second text will be on the same line")
print("Unlike this text which will be on a newline")
Output
>>>
This first text and second text will be on the same line
Unlike this text which will be on a newline
print didn't transition from statement to function until Python 3.0. If you're using older Python then you can suppress the newline with a trailing comma like so:
print "Foo %10s bar" % baz,
Because python 3 print() function allows end="" definition, that satisfies the majority of issues.
In my case, I wanted to PrettyPrint and was frustrated that this module wasn't similarly updated. So i made it do what i wanted:
from pprint import PrettyPrinter
class CommaEndingPrettyPrinter(PrettyPrinter):
def pprint(self, object):
self._format(object, self._stream, 0, 0, {}, 0)
# this is where to tell it what you want instead of the default "\n"
self._stream.write(",\n")
def comma_ending_prettyprint(object, stream=None, indent=1, width=80, depth=None):
"""Pretty-print a Python object to a stream [default is sys.stdout] with a comma at the end."""
printer = CommaEndingPrettyPrinter(
stream=stream, indent=indent, width=width, depth=depth)
printer.pprint(object)
Now, when I do:
comma_ending_prettyprint(row, stream=outfile)
I get what I wanted (substitute what you want -- Your Mileage May Vary)
There's some information on printing without newline here.
In Python 3.x we can use ‘end=’ in the print function. This tells it to end the string with a character of our choosing rather than ending with a newline. For example:
print("My 1st String", end=","); print ("My 2nd String.")
This results in:
My 1st String, My 2nd String.
