Exercise function

1. Exercise 1

Topics requirements:
write a function cacluate, any number of numbers may be received, returns a tuple.
The first parameter is the average of all tuples value, the second value is greater than the average number of all.

def cacluate(*args):
    avg = sum(args)/len(args)
    up_avg=[]
    for item in args:
        if item > avg:
            up_avg.append(item)
    return avg,up_avg
print(cacluate(1,2,3,4,5))

Output:

2. English II

Topics requirements:
write a function that takes a string and returns a tuple, 'ehllo WROLD'
number is a capital letter of the first tuple, and the second value is the number of lower-case letters.

def fun(*args):
    upper_count = 0
    lower_count = 0
    for i in args:
        if i.isupper():
            upper_count += 1
        elif i.islower():
            lower_count += 1
        else:
            continue
    return (upper_count, lower_count)

a = 'ehllo,WROLD'
print(fun(*a))

Output:

3. Practice three

Topics requirements:
write function, receiving a list (containing 30 integers) and an integer number k, returns a new list of
function requirements:
corresponding (without k) the elements in reverse order until the list subscript k;
the subscript k and after the reverse elements;
[1,2,3,4,5] 2 [2,1,5,4,3]

import random

list = []

def fun(alist, k):
    if k < 0 or k > len(alist):
        return 'error key'
    return alist[:k][::-1] + alist[k:][::-1]

print(fun([1, 2, 3, 4, 5], 2))

Output:
