make 3 codes using python: 2 ways to convert decimal into binary code and 1 way to convert binary into decimal code   You are only allowed to use the following functions/methods: print(), range(), len(), sum(), max(), min(), and .append(). It is not mandatory to use all of these functions/methods.

Please help me to make the Flowchart and Paseudocode of my coding script below. Please! I will appriciate your help. # Program make a simple calculatorfrom itertools import permutations,combinationsimport statistics# This function adds two numbersdef add(x, y):return x + y # This function subtracts two numbersdef subtract(x, y):return x - y # This function multiplies two numbersdef multiply(x, y):return x * y # This function divides two numbersdef divide(x, y):return x / y def permutationfun(arr,length):perm = permutations(arr, length)return perm def combinationfun(arr,length):comb=combinations(arr,length)return comb def stats(marks):lengths = [x for x in marks.values()]n = len(lengths)get_sum = sum(lengths)mean = get_sum / nlengths.sort()if n % 2 == 0:median1 = lengths[n//2]median2 = lengths[n//2 - 1]median = (median1 + median2)/2else:median = lengths[n//2]data = Counter(lengths)get_mode = dict(data)mode = [k for k, v in get_mode.items() if v == max(list(data.values()))] if len(mode)…

What benefits can you get from using a function?

In Python how would you return a value from a function?
