>>>keys = ['a', 'b', 'c'] >>>values = [1, 2, 3] >>>dictionary = dict(zip(keys, values)) >>>print(dictionary) >>>x = dict() >>>x这个代码的输出结果是什么

在 Python 交互式环境中执行这段代码,输出结果为:
```
{'a': 1, 'b': 2, 'c': 3}
{}
```
第一行代码输出了一个字典对象,其键值对分别为 {'a': 1, 'b': 2, 'c': 3}。
第二行代码创建了一个空的字典对象,但是并没有输出任何结果,因此第三行的代码 x 输出为空。

keys = [['a'], 'b', 'c'] values = [1, 2, 3] dictionary = dict(zip(keys, values))
This code creates a dictionary where the keys are the elements in the list 'keys' and the values are the corresponding elements in the list 'values'.
In this specific case, the keys list contains a nested list with a single string element 'a', and two other string elements 'b' and 'c'. The values list contains three integer values, 1, 2, and 3.
The zip() function combines the two lists into a list of tuples, where each tuple contains one key-value pair.
The dict() function then converts this list of tuples into a dictionary, with the first element in each tuple (the key) being the dictionary key and the second element (the value) being the corresponding dictionary value.
The resulting dictionary would look like this: {'a': 1, 'b': 2, 'c': 3}
keys = ['a', 'b', 'c'] values = [1, 2, 3] dictionary = dict(zip(keys, values)) print(dictionary) x = dict() x这个代码的执行结果是什么
这段代码定义了两个列表 keys 和 values,然后使用 zip 函数将它们打包为一个元组的列表,再使用 dict 函数将这个列表转换为字典。因此,打印 dictionary 的结果为 {'a': 1, 'b': 2, 'c': 3}。
接下来,定义了一个空字典 x,因此执行这段代码不会有输出结果。
