Session : 8

Objective

• Write a closure that takes a function and then check whether the function passed has a docstring with more than 50 characters. 50 is stored as a free variable - 200

• Write a closure that gives you the next Fibonacci number - 100

• We wrote a closure that counts how many times a function was called. Write a new one that can keep a track of how many times add/mul/div functions were called, and update a global dictionary variable with the counts - 250

• Modify above such that now we can pass in different dictionary variables to update different dictionaries - 250

• Write a test file, that tests all of the functions mentioned above and also includes the other basic ones.

• Test file must contain at least 1 tests for each function.

Solution:

function implemented are check_fn_docs, next_fibo_number, mul, add, div, function_counter, function_two_dict

Functions

Serial No	Name	Functionality
1	check_fn_docs	The function takes in function as parameters and returns True/False based on length of docstring is greater than 50 characters or not
2	next_fibo_number	This function returns the next number from fibnocci series
3	function_counter	The function takes in function as parameters and returns the global dictionary which gives the frequency of each function
4	function_two_dict	The function takes in function as parameters and returns the separate dictionary which gives the frequency of each function for different user

Files

• Test File : PyTest file
• Code: Method Implemantation
