As of Python 3 4 one can use the pathlib module to solve this   If you happen to be on an older version  you can use the backported version found here  Let s assume you are not in the root path  just to add a bit of difficulty to it  you want to rename  and have to provide a full path  we can look at this    some path    a b c the file extension    So  you can take your path and create a Path object out of it   from pathlib import Path p   Path some path    Just to provide some information around this object we have now  we can extract things out of it  For example  if for whatever reason we want to rename the file by modifying the filename from the file to the file 1  then we can get the filename part   name without extension   p stem   And still hold the extension in hand as well    ext   p suffix   We can perform our modification with a simple string manipulation   Python 3 6 and greater make use of f-strings   new file name   f  name without extension  1    Otherwise   new file name           format name without extension  1    And now we can perform our rename by calling the rename method on the path object we created and appending the ext to complete the proper rename structure we want   p rename Path p parent  new file name   ext     More shortly to showcase its simplicity    Python 3 6    from pathlib import Path p   Path some path  p rename Path p parent  f  p stem  1  p suffix       Versions less than Python 3 6 use the string format method instead   from pathlib import Path p   Path some path  p rename Path p parent             format p stem  1  p suffix

One important point to note here  we should check if any files exists with the new filename  suppose if b kml file exists then renaming other file with the same filename leads to deletion of existing b kml  import os  if not os path exists  b kml       os rename  a txt   b kml
