您可以反转dict1以便于操作,然后按如下所示更新list_of_dicts:
你可以将第一个字典的键按它们的值排序,然后用排序后的键顺序从第二个字典构建一个新的字典:
在英语口语交流中,我们通常会将上述Python代码的Docstrings表述为:“The ‘square’ function calculates the square value of a number ‘n’. The ‘greet’ function greets a person named ‘name’ and it varies based on whether it’s morning or not.” Python的PEP 257(Python Enhancement Proposal,Pyth...
