Python program to calculate electricity bill

In this tutorial, we will discuss the Python program to calculate electricity bill

In this post, we will learn how to calculate electricity bill using if condition in the Python programming language

We can calculate monthly consumed electric power usage in many ways.

In this tutorial, we will explain two programs calculating electricity bill in the Python language.

Python program to calculate electricity bill — calculate the electricity bill in the Python language

Before we discuss a program to calculate the electricity bill, we must understand electricity charges and rates.

/*
1 - 100 unit - 1.5/= 
101-200 unit - 2.5/= 
201-300 unit - 4/= 
300 - 350 unit - 5/=
above 300 - fixed charge 1500/=
for example
*/

This program can explain as follows

Declare total unit consumed by the customer using the variable unit.
If the unit consumed less or equal to 100 units, calculates the total amount of consumed =units*1.5
If the unit consumed between 100 to 200 units, calculates the total amount of consumed=(100*1.5)+(unit-100)*2.5)
If unit consumed between 200 to 300 units ,calculates total amount ofconsumed=(100*1.5)+(200-100)*2.5+(units-200)*4
If unit consumed between 300-350 units ,calculates total amount of consumed=(100*1.5)+(200-100)*2.5+(300-200)*4+(units-350)*5
If the unit consumed above 350 units, fixed charge – 1500/=

additional charges

if units<=100 – 25.00
if 100< units and units<=200 – 50.00
if 200 < units and units<=300 – 75.00
if 300<units and units<=350 – 100.00
if units above 350 – No additional charges

Electricity bill calculation – with out and operator

program 1

#program for calculating electricity bill in Python
units=int(input("please enter the number of units you consumed in a month"))
if(units<=100):
    payAmount=units*1.5
    fixedcharge=25.00
elif(units<=200):
    payAmount=(100*1.5)+(units-100)*2.5
    fixedcharge=50.00
elif(units<=300):
    payAmount=(100*1.5)+(200-100)*2.5+(units-200)*4
    fixedcharge=75.00
elif(units<=350):
    payAmount=(100*1.5)+(200-100)*2.5+(300-200)*4+(units-300)*5
    fixedcharge=100.00
else:
    payAmount=0
    fixedcharge=1500.00

Total=payAmount+fixedcharge;
print("\nElecticity bill=%.2f" %Total)

When the above code is executed, it produces the following results

Case 1

please enter the number of units you consumed in a month: 100

Electicity bill=175.00

Case 2

please enter the number of units you consumed in a month: 201

Electricity bill=479.00

Case 3

please enter the number of units you consumed in a month: 301

Electricity bill=905.00

Case 4

please enter the number of units you consumed in a month: 351

Electricity bill=1500.00

Electricity bill calculation – with and operator

Program 2

#program for calculating electricity bill in Python using and operator
units=int(input("Number of unit consumed: "))
if(units>0 and units<=100):
    payAmount=units*1.5
    fixedcharge=25.00
elif(units>100 and units<=200):
    payAmount=(100*1.5)+(units-100)*2.5
    fixedcharge=50.00
elif(units>200 and units<=300):
    payAmount=(100*1.5)+(200-100)*2.5+(units-200)*4
    fixedcharge=50.00
elif(units>300):
    payAmount=2500;#fixed rate
    fixedcharge=75.00
else:
    payAmount=0;
    
Total= payAmount+fixedcharge
print("\nElecticity bill pay=%.2f: " %Total);

When the above code is executed, it produces the following results

Number of unit consumed: 234
Electricity bill pay=586.00:
