Remove and Replace Printed items

Question

I was wondering if it was possible to remove items you have printed in Python - not from the Python GUI  but from the command prompt  e g   a   0   for x in range  0 3         a   a   1       b     Loading          a  print  a    so it prints   gt  gt  gt Loading     gt  gt  gt Loading    gt  gt  gt Loading     gt  gt  gt Loading      But  my problem is I want this all on one line  and for it it remove it self when something else comes along  So instead of printing  Loading    Loading     Loading    I want it to print  Loading    then it removes what is on the line and replaces it with  Loading    and then removes  Loading    and replaces it  on the same line  with  Loading      It s kind of hard to describe   p s I have tried to use the Backspace character but it doesn t seem to work    b    Thanks

Just use CR to go to beginning of the line   import time for x in range  0 5         b    Loading          x     print  b  end   r       time sleep 1

One way is to use ANSI escape sequences   import sys import time for i in range 10       print  Loading          i      sys stdout write   033 F     Cursor up one line     time sleep 1    Also sometimes useful  for example if you print something shorter than before    sys stdout write   033 K     Clear to the end of line

import sys import time  a   0   for x in range  0 3         a   a   1       b     Loading          a         r prints a carriage return first  so  b  is printed on top of the previous line      sys stdout write   r  b      time sleep 0 5  print  a    Note that you might have to run sys stdout flush   right after sys stdout write   r  b  depending on which console you are doing the printing to have the results printed when requested without any buffering
