# 练习：
|
||
# 1.利用函数实现传入一个年份，判断是否是闰年
|
||
def is_run(year): # year:形参，占位
|
||
if year % 4 == 0 and year % 100 !=0 or year % 400 == 0:
|
||
return '闰年'
|
||
else:
|
||
return '非闰年'
|
||
|
||
# 调用三次函数
|
||
# print(is_run(2000))
|
||
# print(is_run(2001))
|
||
# print(is_run(2002))
|
||
|
||
# 2.利用函数实现两个数字的加减乘除
|
||
# 分析：参数
|
||
# def calc(n1,n2,op): # n1,n2都是数字，op是操作符
|
||
# if op == '+':
|
||
# return n1 + n2
|
||
# elif op == '-':
|
||
# return n1 - n2
|
||
# elif op == '*':
|
||
# return n1 * n2
|
||
# elif op == '/':
|
||
# return n1 / n2
|
||
# else:
|
||
# return '输入有误!'
|
||
# print(calc(1,2,'+'))
|
||
# print(calc(1,2,'-'))
|
||
# print(calc(1,2,'*'))
|
||
# print(calc(1,2,'/'))
|
||
|
||
# 3.函数实现：请输入一个km数值，计算打车费用，已知出租车起步价10块钱3km以内，超出的部分2元/km
|
||
# def car_money(km):
|
||
# if km > 3:
|
||
# return 10 + (km-3)*2
|
||
# else:
|
||
# return 10
|
||
|
||
# print(car_money(5))
|
||
# print(car_money(2))
|
||
# print(car_money(10))
|
||
|
||
# 4.函数实现：根据公式(身高-108)*2 = 体重，可以有10斤左右的浮动，来观察测试者体重是否标准(身高：cm)
|
||
def calc(height,weight):
|
||
max = (height - 108)*2 + 10 # 最大限度
|
||
min = (height - 108)*2 - 10 # 最小限度
|
||
if weight > max:
|
||
return '偏胖'
|
||
elif weight < min:
|
||
return '偏瘦'
|
||
elif min<=weight<=max:
|
||
return '标准身材'
|
||
else:
|
||
return '输入有误'
|
||
|
||
print(calc(170,180))
|
||
print(calc(170,110))
|
||
print(calc(170,130))
