Description

Using itertools library to group repeated letters in the string and encode them with the help of function that returns a generator by using key word yield. This task is so called also as basic compressing task.

Algorithm:

  • Finding all repeated letters and calculating them.
  • Returning encoded string with number + letter.
  • No number for letters that are met only once.

Example:

  • input string: aaaBBBBBaCCCCcFfff
  • Encoded string: 3a5Ba4CcF3f
