I don't know how to achieve this programmatically: sorted by the
number of occurrences in a descending order. If two or more words
have the same count, they should be sorted
alphabetically (in an ascending order).

I need a custom comparator.
dictionary = {a:[b,c], d:[e,f]}
If both 'b' and 'e' belong to the same bin
then it should be compared based on 'c' and 'f'.
However, I want to also represent the result of the
sorted operation in a ordered dictionary as order is
important.
My custom comparator is
Trying to use decorators in my class. I am calling
build_tree from the main function and i want to increment
the arguments by a constant factor by using decorators.
However as build_tree is a recursive function, I don't want
to call it recursively with increased constant factor always.

I am trying to implement grep to just increase my knowledge
about regular expression.
Below is the program usage:
python test.py -i Documents/linux/linux/ -s '\w+_readalarm*'
However, due to my lack of knowledge about string handling
in python, I am getting wrong results.
