Cloud Studio代码运行 print(merge_two_dicts(x,y)) 如果还想合并不定数量的字典,如3个字典、5个字典,可以使用下面的函数: 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 defmerge_dicts(*dict_args):result={}fordictionaryindict_args:result.update(dictionary)returnresult new_dict={'x':20...
z = merge_two_dicts(x, y) 1. 你还可以创建一个函数来合并未定义数量的dict,从零到非常大的数字: def merge_dicts(*dict_args): """ Given any number of dicts, shallow copy and merge into a new dict, precedence goes to key value pairs in latter dicts. """ result = {} for dictionary...
"""Given two dicts, merge them into a new dict as a shallow copy.""" z = x.copy() z.update(y) return z 然后一行代码完成调用: z = merge_two_dicts(x, y) 你也可以定义一个函数,合并多个dict,例如 def merge_dicts(*dict_args): """ Given any number of dicts, shallow copy and me...
# Define a function 'merge_dictionaries' that takes a variable number of dictionaries ('*dicts') as arguments. # It merges the dictionaries into a new dictionary and returns the result. def merge_dictionaries(*dicts): # Create an empty dictionary 'result' to store the merged key-value pairs...

我的回答是: merge_two_dicts(x, y) 如果我们真的关心可读性,对我来说实际上似乎更清楚。而且它不向前兼容,因为 Python 2 越来越被弃用。{**x, **y} 似乎不处理嵌套字典。嵌套键的内容只是被覆盖,而不是合并[…]我最终被这些不递归合并的答案烧毁了,我很惊讶没有人提到它。在我对“合并”一词的解释...
