Python Slip 2

Q1. Write a python program to show how to use else clause with try and except clauses.

def calculate_bmi(height, weight):
    """ calculate body mass index (BMI) """
    return weight / height**2

def evaluate_bmi(bmi):
    """ evaluate the bmi """
    if 18.5 <= bmi <= 24.9:
        return 'healthy'
    if bmi >= 25:
        return 'overweight'
    return 'underweight'

def slip2():
    try:
        height = float(input('Enter your height (meters):'))
        weight = float(input('Enter your weight (kilograms):'))

    except ValueError as error:
        print(error)
    else:
        bmi = round(calculate_bmi(height, weight), 1)
        evaluation = evaluate_bmi(bmi)

        print(f'Your body mass index is {bmi}')
        print(f'This is considered {evaluation}!')
        
slip2()

OUTPUT

Enter your height (meters):1.4
Enter your weight (kilograms):75
Your body mass index is 38.3
This is considered overweight!

Q2. Write a python program to count and display even and odd numbers of a List.

list1 = [21,3,4,6,33,2,3,1,3,76]
even_count, odd_count = 0, 0
# enhanced for loop
for num in list1:
   #even numbers
   if num % 2 == 0:
      even_count+= 1
   #odd numbers
   else:
      odd_count+= 1
print("Even numbers available in the list: ", even_count)
print("Odd numbers available in the list: ", odd_count)

OUTPUT

Even numbers available in the list:  4
Odd numbers available in the list:  6

Q2. Write a python program to find sum of items of a Dictionary.

def Sum(dic):
    sum=0
    #iterate through values
    for i in dic.values():
        sum=sum+i
    return sum

dic={ 'x':30, 'y':40, 'z':50 }
print("Dictionary: ", dic)
print("sum: ",Sum(dic))

OUTPUT

Dictionary:  {'x': 30, 'y': 40, 'z': 50}
sum:  120
