python从0到1--6.if选择语句

1.if语句

直接上干货：

例1:

number = int(input("请输入您的6位奖票号码"))
if number == 432678:
    print("恭喜您中奖了")
if number != 432678:
    print("很遗憾，您未中奖")

2.if...else语句

number = int(input("请输入您的6位奖票号码"))
if number == 432678:
    print("恭喜您中奖了")
else:
    print("很遗憾，您未中奖")

3.if...elif...else语句

number = int(input("请输入商品7天销量："))
if number >= 1000:
    print("商品7天销量为A！")
elif number >=500:
    print("商品7天销量为B！")
elif number >= 300:
    print("商品7天销量为C！")
else:
    print("商品7天销量为D！")

4.if语句嵌套

number = int(input("请输入商品7天销量："))
if number >= 1000:
    print("商品7天销量为A！")
else:
    if number >=500:
        print("商品7天销量为B！")
    else:
        if number >= 300:
            print("商品7天销量为C！")
        else:
            print("商品7天销量为D！")

5.使用and/or/not链接条件

例1:

age = int(input("请输入您的年龄："))
if age > 18 and age < 78:
    print("您可以申请汽车驾驶证")
else:
    print("您的年龄不满足！")

例2:

sales = int(input("请输入商品日销量："))
if sales < 10 or sales > 100:
    print("该商品为重点关注商品")

例3:

a = input("请输入1位数字密码")
b = ["0","1","2","3","4","5","6","7","8","9"]
if a not in b:
    print("非法输入")
