代码实现如下: defmerge_dicts(*dict_args):result={}foritemindict_args:result.update(item)returnresultx1={'a':1,'b':2}y1={'b':4,'c':5}x2={'d':8,'e':10}z3=merge_dicts(x1,y1,x2)print(z3)结果:{'a':1,'b':4,'c':5,'d':8,'e':10} 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16.
Python 中两个字典(dict)合并 dict1 = {"name":"owen","age":18} dict2 = {"birthday":"1999-11-22","height":180} 合并两个字典得到: 方法1: dictMerged1 = dict( list(dict1.items()) + list(dict2.items()) )
Python 3.9 introduced the merge operator|, which allows you to concatenate dictionaries in a single line. Syntax: Here is the syntax: dict3 = dict1 | dict2 Example: Now, let me show you a complete example. user_info1 = {'name': 'John Doe', 'age': 30} user_info2 = {'city': ...

通过使用Python中的update()方法,可以将一个列表合并到另一个列表中。但是在这种情况下,第二个列表被合并到第一个列表中,并且没有创建新的列表。它返回None。 示例: def merge(dict1, dict2): return(dict2.update(dict1)) # Driver code dict1 = {'a': 10, 'b': 8} ...
