介绍
主要分为3大类：
keys() 、values() 、items()

2 遍历 key 值
方法一：

data = {‘A’: 1, ‘B’: 3, ‘C’: 5}

for key in data.keys():
print(f'{key}: {data[key]}’)

3 遍历 value 值
data = {‘A’: 1, ‘B’: 3, ‘C’: 5}

for values in data.values():
print(f'{values}’)

4 遍历字典项
data = {‘A’: 1, ‘B’: 3, ‘C’: 5}

for kv in data.items():
print(f'{kv}’)

5 遍历字典 键值
data = {‘A’: 1, ‘B’: 3, ‘C’: 5}

for key, value in data.items():
print(f'{key}: {value}’)

data = {‘A’: 1, ‘B’: 3, ‘C’: 5}

for (key, value) in data.items():
print(f'{key}: {value}’)
