本文介绍了一个简单的程序,可以用于计算电费单,适用于家庭、公寓、办公室等场所。该程序将输入电表读数,并按照电力公司的费率计算电费,最后输出账单。
该程序需要输入两个数字:上月电表读数和本月电表读数。可以通过键盘输入,也可以从一个文件中读取。
# 从键盘输入
last_meter_reading = int(input("请输入上月电表读数: "))
this_month_meter_reading = int(input("请输入本月电表读数: "))
# 从文件中读取
with open('meter_readings.txt') as f:
lines = f.readlines()
last_meter_reading = int(lines[0])
this_month_meter_reading = int(lines[1])
该程序适用于中国电力公司(CHINA POWER)的计费标准。按照当前费率,电费由两部分组成:基本电费和阶梯电费。基本电费每度电0.65元,不受用电量的多少影响。阶梯电费根据用电量进行计算,用电量越多,单价越高。
用电量(本月电表读数 - 上月电表读数)小于等于150度时,阶梯电费为0元。用电量大于150度小于等于400度时,阶梯电费为0.8元/度。用电量大于400度时,阶梯电费为1.0元/度。
# 计算用电量
electricity_consumption = this_month_meter_reading - last_meter_reading
# 计算基本电费
basic_electricity_cost = 0.65 * electricity_consumption
# 计算阶梯电费
if electricity_consumption > 400:
tiered_electricity_cost = (electricity_consumption - 400) * 1.0 + (400 - 150) * 0.8
elif electricity_consumption > 150:
tiered_electricity_cost = (electricity_consumption - 150) * 0.8
else:
tiered_electricity_cost = 0
# 计算总电费
total_electricity_cost = basic_electricity_cost + tiered_electricity_cost
最后,该程序会输出一个电费单,包括上月电表读数、本月电表读数、用电量、基本电费、阶梯电费和总电费。
print("上月电表读数:{}".format(last_meter_reading))
print("本月电表读数:{}".format(this_month_meter_reading))
print("用电量:{}度".format(electricity_consumption))
print("基本电费:{:.2f}元".format(basic_electricity_cost))
print("阶梯电费:{:.2f}元".format(tiered_electricity_cost))
print("总电费:{:.2f}元".format(total_electricity_cost))
# 从键盘输入
last_meter_reading = int(input("请输入上月电表读数: "))
this_month_meter_reading = int(input("请输入本月电表读数: "))
# 从文件中读取
# with open('meter_readings.txt') as f:
# lines = f.readlines()
# last_meter_reading = int(lines[0])
# this_month_meter_reading = int(lines[1])
# 计算用电量
electricity_consumption = this_month_meter_reading - last_meter_reading
# 计算基本电费
basic_electricity_cost = 0.65 * electricity_consumption
# 计算阶梯电费
if electricity_consumption > 400:
tiered_electricity_cost = (electricity_consumption - 400) * 1.0 + (400 - 150) * 0.8
elif electricity_consumption > 150:
tiered_electricity_cost = (electricity_consumption - 150) * 0.8
else:
tiered_electricity_cost = 0
# 计算总电费
total_electricity_cost = basic_electricity_cost + tiered_electricity_cost
# 输出账单
print("上月电表读数:{}".format(last_meter_reading))
print("本月电表读数:{}".format(this_month_meter_reading))
print("用电量:{}度".format(electricity_consumption))
print("基本电费:{:.2f}元".format(basic_electricity_cost))
print("阶梯电费:{:.2f}元".format(tiered_electricity_cost))
print("总电费:{:.2f}元".format(total_electricity_cost))
该程序只适用于中国电力公司的计费标准,其他地区的电费计算方式可能存在差异。此外,该程序只是一个简单的示例,开发者可以根据实际需求进行修改和扩展。
