1、基本機構
info = {
    "k1": "v1", # 鍵值對
    "k2": "v2"
}
### 2 字典的value可以是任何值
info = {
    "k1": 18,
    "k2": True,
    "k3": [
        11,
        [],
        (),
        
 
22,
        33,
        {
            'kk1': 'vv1',
            'kk2': 'vv2',
            'kk3': (11,22),
        }
    ],
    "k4": (11,22,33,44)
}
print(info)

###  3 布林值(1,0)、列表、字典不能作為字典的key
info ={
    1: 'asdf',
    "k1": 'asdf',
    True: "123",
    # [11,22]: 123
    (11,22): 123,
    
 
# {'k1':'v1'}: 123

}
print(info)

4 字典無序

info = {
    "k1": 18,
    "k2": True,
    "k3": [
        11,
        [],
        (),
        22,
        33,
        {
            'kk1': 'vv1',
            'kk2': 'vv2',
            'kk3': (11,22),
        }
    ],
    "k4": (11,22,33,44)
}
 
print(info)

5、索引方式找到指定元素
info = {
    "k1": 18,
    2: True,
    "k3": [
        11,
        [],
        (),
        22,
        33,
        {
            'kk1': 'vv1',
            'kk2': 'vv2',
            'kk3': (11,22),
        }
    ],
    "k4": (11,22,33,44)
}
# v = info['k1']
# print(v)
# v = info[2]
# print(v)
v = info['k3'][5]['kk3'][0]
print(v)

6 字典支援 del 刪除
info = {
    "k1": 18,
    2: True,
    "k3": [
        11,
        [],
        (),
        22,
        33,
        {
            'kk1': 'vv1',
            'kk2': 'vv2',
            'kk3': (11,22),
        }
    ],
    "k4": (11,22,33,44)
}
del info['k1']

del info['k3'][5]['kk1']
print(info)
