前置知识 for 循环详解:https://www.cnblogs.com/poloyy/p/15087053.html 使用 for key in dict 遍历字典 可以使用 for key in dict 遍历字典中所有的键 x = {'a': 'A', 'b': 'B'} for key in x: print(key) # 输出结果 a b 使用 for key in dict.keys () 遍历字典的键 字典提供了 keys () 方法返回字典中所有的键 # keys book =…
#遍历字典, 分别打印key, value, key:value emp = {'name':'Tom', 'age':20, 'salary' : 8800.00} for k in emp.keys(): print('key = {}'.format(k)) for v in emp.values(): print('values = {}'.format(v)) for v,k in emp.items(): print('{v}:{k}'.format(v = v, k = k)) 打…
此系列之后将参考一些最常用功能的在线教程/示例程序, 进行示例代码的中文化改进. 欢迎推荐有代表性和实用性的教程, 篇幅小更佳. 谢谢. 参考Python - How to loop a dictionary 下面将介绍如何在Python中遍历一个字典 1. for 键 in 字典: 1.1 对字典中所有的键进行遍历 - for 键 in 字典: for 键 in 字典: print(键) 1.2 遍历字典中所有的键和对应值 - for 键, 值 in 字典.items(): for 键, 值…
