Functions

1. Write a function that computes the volume of a sphere given its radius.

The volume of a sphere is given as $$ \frac{4}{3} πr^3 $$

Answer

def vol(rad):
    volume = (4/3)*3.14*rad*rad*rad
    print(volume)

vol(2)

2. Write a function that checks whether a number is in a given range (inclusive of high and low)

Answer

def num_check(num,low,high):
    if num in range(low,high+1):
        print(f'{num} is in the range between {low} and {high}')
    else:
        print(f'{num} is out of range')

num_check(5,2,7)

To return only boolean value

def num_bool(num,low,high):
    return num in range(low,high+1)

num_bool(5,2,7)

3. Write a Python function that takes a list and returns a new list with unique elements of the first list.

Sample List : [1,1,1,1,2,2,3,3,3,3,4,5]
Unique List : [1, 2, 3, 4, 5]

4. Write a Python function to multiply all the numbers in a list.

Sample List : [1, 2, 3, -4]
Expected Output : -24

5. Write a Python function that accepts a string and calculates the number of upper case letters and lower case letters.

Sample String : 'Hello Mr. Rogers, how are you this fine Tuesday?'
Expected Output : 
No. of Upper case characters : 4
No. of Lower case Characters : 33

Hint: Two string methods that might prove useful: .isupper() and .islower()
