Python 程序：计算电费

用实例编写 Python 程序计算电费。为此，我们使用了 Elif 语句。

这个 python 程序允许用户输入用户消耗的单位。接下来，Python 计算总电费。如果电力局对不同的设备收取不同的费用，这种方法是有用的。对于这个例子，我们使用的是 Elif 语句。

# Python Program to Calculate Electricity Bill

units = int(input(" Please enter Number of Units you Consumed : "))

if(units < 50):
    amount = units * 2.60
    surcharge = 25
elif(units <= 100):
    amount = 130 + ((units - 50) * 3.25)
    surcharge = 35
elif(units <= 200):
    amount = 130 + 162.50 + ((units - 100) * 5.26)
    surcharge = 45
else:
    amount = 130 + 162.50 + 526 + ((units - 200) * 8.45)
    surcharge = 75

total = amount + surcharge
print("\nElectricity Bill = %.2f"  %total)

如果电路板具有统一的速率，则该 Python 代码非常有用。类似于:如果你消耗 300 到 500 个单位，那么单位固定为 7.75 卢比，等等。让我们看看 python 程序

提示: Elif 语句先检查蟒的情况。如果为真，则执行该块中的语句。如果条件为假，则 python 程序检查下一个条件(Elif 条件)等等。

# Python Program to Calculate Electricity Bill

units = int(input(" Please enter Number of Units you Consumed : "))

if(units > 500):
    amount = units * 9.65
    surcharge = 85
elif(units >= 300):
    amount = units * 7.75
    surcharge = 75
elif(units >= 200):
    amount = units * 5.26
    surcharge = 55
elif(units >= 100):
    amount = units * 3.76
    surcharge = 35
else:
    amount = units * 2.25
    surcharge = 25

total = amount + surcharge
print("\nElectricity Bill = %.2f"  %total)

蟒电程序输出

 Please enter Number of Units you Consumed : 450

Electricity Bill = 3562.50
>>> 
 Please enter Number of Units you Consumed : 750

Electricity Bill = 7322.50
>>> 
 Please enter Number of Units you Consumed : 250

Electricity Bill = 1370.00
>>> 
 Please enter Number of Units you Consumed : 150

Electricity Bill = 599.00
>>> 
 Please enter Number of Units you Consumed : 50

Electricity Bill = 137.50
