# What reduce does?
|
|
|
|
# reduce take the function given and take item from the
|
|
# iterable and pass to function given to it. The first
|
|
# parameter is the value initialized as the 3rd argument
|
|
# to the reduce function. It do the processing and returns
|
|
# a value which is used as next initialiizing value for the
|
|
# first argument of the function provided in the reduce function
|
|
# and so on for all items in iterable. |
