Python Day 4-Project on EMI,BMI,SSLC %,EB Bill calculator

1. EMI calculator:

p= float(input("Enter the loan amount Principal: "))

annual_rate = float(input("Enter the annual interest rate: "))
R = (annual_rate / 100) / 12

years = int(input("Enter the loan tenure: "))

N = years * 12


emi = (P * R * (1 + R)**N) / ((1 + R)**N - 1)

print("your emi amount is:",emi)

If we enter the values of principal amount,rate of annual interest,tenure of the loan then the result will be like this,

Enter the loan amount Principal: 100000
Enter the annual interest rate: 10
Enter the loan tenure: 10
your emi amount is: 1321.5073688176194

2. Sslc percentage calculation:

tamil = input("Tamil Mark please: ")
english = input("English Mark please: ")
maths = input("Maths Mark please: ")
science = input("Science Mark please: ")
social = input("Social Mark please: ")
print(int(tamil) + int(english) + int(maths) + int(science) + int(social))

total=int(tamil) + int(english) + int(maths) + int(science) + int(social)
print("Your overall marks percentage is",(total/500*100))

So for the above syntax by entering all subject marks then the output will be,

Tamil Mark please: 83
English Mark please: 89
Maths Mark please: 83
Science Mark please: 95
Social Mark please: 90
440
Your overall marks percentage is 88.0

3. BMI calculator:

def calculate_bmi(weight,height):
    bmi=weight/(height*height)
    return bmi

weight=int(input("Enter your weight in kg:"))
height=float(input("Enter your height in meters:"))

total=calculate_bmi(weight,height)

print("your bmi is: ",total)

For the above syntax after entering weight(kg) and height(meters) then the output will be

Enter your weight in kg: 70
Enter your height in meters: 1.68
your bmi is 24.801587301587304

4. EB calculator:

def calculate_bill(units,price_per_unit):
    bill=units*price_per_unit
    return bill

units=float(input("Enter the no of units consumed: "))
price_per_unit=float(input("Enter the price per unit: "))

total_bill=calculate_bill(units,price_per_unit)
print("Total electricity bill:",total_bill)

After entering no of units consumed and price per unit the output will be,

Enter the no of units consumed: 200
Enter the price per unit: 10
Total electricity bill: 2000.0
