# Python 字典

字典的基本使用，插入key-value，并打印结果

```python
if __name__ == '__main__':
    map = {}
    map['name'] = "monkey"
    map['age'] = 25
    map['tags'] = "猴子"
    map['tags'] = ['程序员', '户外达人']
    map['profile'] = {'info1': "test", "info2": "test"}

    print(map['tags'])
    print(map['profile'].get("info3"))
```

上述代码的打印结果是？

## template

```python
if __name__ == '__main__':
    map = {}
    print('* 初始化字典:', map)

    print('* 使用下标插入数据到字典')
    map['name'] = "monkey"
    map['age'] = 25
    map['no'] = 10000

    for key in map:
        value = map[key]
        print("{}:{}".format(key, value))

    print('* 字典里可以插入其他数据类型，例如插入列表')
    map['tags'] = ['程序员', '户外达人']
    print('* 打印 tags :{}', map.get('tags'))
    print('* 字典里可以插入其他数据类型，例如插入字典')
    map['profile'] = {'info1': "test", "info2": "test"}
    print('* 打印 profile :{', map.get('profile'))
```
