《Python编程 从入门到实践》day9

昨日知识点回顾：

        遍历字典键、值、键值对

        input()获取用户输入

        while循环、bieak、continue

今日知识点学习：

        7.3 使用while循环处理列表和字典

                7.3.1 在列表之间移动元素

list1 = ['监控','监视','监察']
list2 = []

while list1:
    list = list1.pop()
    print(list)
    list2.append(list)

print(list1)
print(list2)

# 运行结果：
# 监察
# 监视
# 监控
# []
# ['监察', '监视', '监控']

                7.3.2 删除特定值的所有列表元素

list = ['监控','监视','监控','监察','监看','监控']

while '监控' in list:
    list.remove('监控')

print(list)

# 运行结果：
# ['监视', '监察', '监看']

                7.3.3 使用用户输入来填充字典

answers = {}
tag = True
while tag:
    name = input("What's your name?")
    age = input("How old are you?")

    answers[name] = age
    repeat = input('Would you want to tell me your age?(yes/no)')
    if repeat == 'no':
        tag = False

print(answers)

# 运行结果：
# What's your name?Bob
# How old are you?18
# Would you want to tell me your age?(yes/no)yes
# What's your name?Sunny
# How old are you?19
# Would you want to tell me your age?(yes/no)no
# {'Bob': '18', 'Sunny': '19'}
