a   5 print   02d    a   output  05   The     operator is called string formatting operator when used with a string on the left side    d  is the formatting code to print out an integer number  you will get a type error if the value isn t numeric   With   2d you can specify the length  and   02d  can be used to set the padding character to a 0 instead of the default space

If you are an analyst and not a full stack guy  this might be more intuitive     str  00000     str i   -5   for i in arange 100     breaking that down  you    start by creating a list that repeats 0 s or X s  in this case  100 long  i e   arange 100  add the numbers you want to the string  in this case  numbers 0-99  i e    i  keep only the right hand 5 digits  i e     -5    for subsetting output is numbered list  all with 5 digits

This is a dumb solution but I was getting type errors with the other solutions above  So if all else fails  yolo   images3digit       for i in images          if len i   1              i    00  i             images3digit append i          elif len i   2              i    0  i             images3digit append i          elif len i   3              images3digit append i

Based on what  user225312 said  you can use  zfill   to add paddng to numbers converted to strings  My approach is to leave number as a number until the moment you want to convert it into string   gt  gt  gt  num   11  gt  gt  gt  padding   3  gt  gt  gt  print str num  zfill padding   011
