為 EB 帳單計算器編寫程序

電費帳單計算器：

電費 (EB) 計算器是一種用於根據消耗的單位和適用的電價估算用電量成本的工具。

公式：
電費=用電量（kWh）x每度電價。

範例：

# Function to calculate electricity bill based on unit consumption
def eb(unit):
    # First 100 units are free
    if unit <= 100:
        cost = 0.00
    # For 101–200 units, charge ₹2.50 per unit above 100
    elif unit <= 200:
        cost = (unit - 100) * 2.50
    # For 201–300 units, add ₹3.00 per unit above 200
    elif unit <= 300:
        cost = 100 * 2.5 + (unit - 200) * 3.00
    # For 301–400 units, add ₹4.50 per unit above 300
    elif unit <= 400:
        cost = 100 * 2.5 + 100 * 3 + (unit - 300) * 4.50
    # For units above 400, add ₹6.00 per unit above 400
    else:
        cost = 100 * 2.5 + 100 * 3 + 100 * 4.5 + (unit - 400) * 6.00
    # Return the total calculated cost
    return cost

# input the total units consumed
unit = int(input("Enter the unit: "))

# Call the `eb` function to calculate the electricity bill
eb_bill = eb(unit)

# Display the calculated electricity bill amount
print("Electricity bill amount:", eb_bill)

輸出：

Enter the unit:345
Electricity bill amount: 752.5
