python---字典遍歷

1、三種常見的字典遍歷實現

def get_key_value(dics):
    '''遍歷所有鍵值對'''
    for key, value in dics.items():
        print(f"{key}: {value}")

def get_keys(dics):
    ''' 遍歷所有的鍵'''
    for key in dics.keys():
        print(key)

def get_values(dics):
    '''遍歷所有的值'''
    for value in dics.values():
        print(value)

if __name__ == "__main__":
    dics = {
        'name': 'xiaopangyu',
        'age': 18,
        'sex': 'man',
        'high': 180
    }

    # 三種字典遍歷方法
    print("========== 遍歷所有的key value ==========")
    get_key_value(dics)
    print("========== 遍歷所有的key ==========")
    get_keys(dics)
    print("========== 遍歷所有的value ==========")
    get_values(dics)

　　2、列印結果

name: xiaopangyu
age: 18
sex: man
high: 180
========== 遍歷所有的key ==========
name
age
sex
high
========== 遍歷所有的value ==========
xiaopangyu
18
man
180
