you want to print something in for loop right but you don t want it print in new line every time   for example    for i in range  0 5      print  hi    OUTPUT      hi     hi     hi     hi     hi     but you want it to print like this  hi hi hi hi hi hi right     just add a comma after print  hi   Example   for i in range  0 5      print  hi   OUTPUT  hi hi hi hi hi

There are general two ways to do this  Print without newline in Python 3 x Append nothing after the print statement and remove   n  by using end     as   gt  gt  gt  print  hello   hello    appending   n  automatically  gt  gt  gt  print  world   world   with previous   n  world comes down    solution is   gt  gt  gt  print  hello   end     print   world      end with anything like end  -  or end  quot   quot  but not   n  hello world   it seem correct output  Another Example in Loop  for i in range 1 10       print i  end       Print without newline in Python 2 x Adding a trailing comma says that after print ignore  n   gt  gt  gt  print  quot hello quot    print quot  world quot  hello world  Another Example in Loop  for i in range 1 10       print  quot      quot  format i    Hope this will help you  You can visit this link

The new  as of Python 3 x  print function has an optional end parameter that lets you modify the ending character   print  HELLO   end     print  HELLO     Output      HELLOHELLO     There s also sep for separator   print  HELLO    HELLO    HELLO   sep       Output        HELLOHELLOHELLO   If you wanted to use this in Python 2 x just add this at the start of your file   from   future   import print function

for i in range 0  5    setting the value of  i  in the range 0 to 5       print i   The above code gives the following output   0      1  2  3  4  But if you want to print all these output in a straight line then all you should do is add an attribute called    end   to print   for i in range 0  5    setting the value of  i  in the range 0 to 5       print i  end  quot   quot    Output   0 1 2 3 4  And not just a space  you can also add other endings for your output  For example   for i in range 0  5    setting the value of  i  in the range 0 to 5       print i  end  quot    quot    Output   0  1  2  3  4    Remember   Note  The  for variable in range int 1  int 2    always prints till the variable is 1   less than it s limit   1 less than int 2

In Python 3  you can use the sep  and end  parameters of the print function   To not add a newline to the end of the string   print      end       To not add a space between all the function arguments you want to print   print  a    b    c   sep       You can pass any string to either parameter  and you can use both parameters at the same time   If you are having trouble with buffering  you can flush the output by adding flush True keyword argument   print      end     flush True    Python 2 6 and 2 7  From Python 2 6 you can either import the print function from Python 3 using the   future   module   from   future   import print function   which allows you to use the Python 3 solution above   However  note that the flush keyword is not available in the version of the print function imported from   future   in Python 2  it only works in Python 3  more specifically 3 3 and later  In earlier versions you ll still need to flush manually with a call to sys stdout flush    You ll also have to rewrite all other print statements in the file where you do this import   Or you can use sys stdout write    import sys sys stdout write        You may also need to call  sys stdout flush     to ensure stdout is flushed immediately

Many of these answers seem a little complicated  In Python 3 x you simply do this   print  lt expr gt    lt expr gt         lt expr gt   end        The default value of end is   n   We are simply changing it to a space or you can also use end     no space  to do what printf normally does

In Python 3  you can use the sep  and end  parameters of the print function   To not add a newline to the end of the string   print      end       To not add a space between all the function arguments you want to print   print  a    b    c   sep       You can pass any string to either parameter  and you can use both parameters at the same time   If you are having trouble with buffering  you can flush the output by adding flush True keyword argument   print      end     flush True    Python 2 6 and 2 7  From Python 2 6 you can either import the print function from Python 3 using the   future   module   from   future   import print function   which allows you to use the Python 3 solution above   However  note that the flush keyword is not available in the version of the print function imported from   future   in Python 2  it only works in Python 3  more specifically 3 3 and later  In earlier versions you ll still need to flush manually with a call to sys stdout flush    You ll also have to rewrite all other print statements in the file where you do this import   Or you can use sys stdout write    import sys sys stdout write        You may also need to call  sys stdout flush     to ensure stdout is flushed immediately

you do not need to import any library  Just use the delete character   BS u  0008    the unicode for  delete  character for i in range 10  print BS         this removes the newline and the space

Many of these answers seem a little complicated  In Python 3 x you simply do this   print  lt expr gt    lt expr gt         lt expr gt   end        The default value of end is   n   We are simply changing it to a space or you can also use end     no space  to do what printf normally does
