python 使用while循环来处理列表和字典

# 使用while循环来处理列表和字典

# 1.在列表间移动元素
# 将user1中的元素移到user2中
user1 = ['a', 'b', 'c', 'd']
user2 = []
while user1:
    temp = user1.pop()  # 弹出元素给temp
    user2.append(temp)

print(user1)  # []
print(user2)  # ['d', 'c', 'b', 'a']

# 2.删除包含特定值的所有列表元素
# 删除列表中相同的值
pets = ['dog', 'cat', 'pig', 'cat']
while 'cat' in pets:
    pets.remove('cat')

print(pets)  # ['dog', 'pig']

# 3.使用用户输入来填充字典
ans = { }
flag = True
while flag:
    name = input('please enter your name:')
    love = input('please enter your the love:')
    ans[name] = love

    message = input('continue enter?yes/no:')
    if message == 'no':
        flag = False
# 循环打印
for name, love in ans.items():
    print(name + 'love' + love)
