Python 程序：計算電費

用實例編寫 Python 程序計算電費。為此，我們使用了 Elif 語句。

這個 python 程序允許用戶輸入用戶消耗的單位。接下來，Python 計算總電費。如果電力局對不同的設備收取不同的費用，這種方法是有用的。對於這個例子，我們使用的是 Elif 語句。

# 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)

如果電路板具有統一的速率，則該 Python 代碼非常有用。類似於:如果你消耗 300 到 500 個單位，那麼單位固定為 7.75 盧比，等等。讓我們看看 python 程序

提示: Elif 語句先檢查蟒的情況。如果為真，則執行該塊中的語句。如果條件為假，則 python 程序檢查下一個條件(Elif 條件)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)

蟒電程序輸出

 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
