You can use thezip()to combine two dictionaries into a dictionary and two lists into a dictionary in Python. We can use the dict() constructor anddictionary comprehensionalong with the zip() to combine into the dictionary very easily. Advertisements In this article, I will explain how we can...

Dictionary comprehension: Creates a new dictionary from an existing list. You can specify different values for each key in the dictionary. Dictionary comprehensions are similar toPython list comprehensionsin structure. zip(): Converts two or more lists into a list of tuples. You can use the dic...
keys=['a','b','c']values=[1,2,3]my_dict=dict(zip(keys,values))print(my_dict) 1. 2. 3. 4. 输出结果将是: {'a': 1, 'b': 2, 'c': 3} 1. 状态图 以下是使用字典推导式将列表转换为字典的状态图: List to DictionaryConvert ...
3. Convert List to Dictionary Using zip() function Thezip() functionis used to combine the two values which are passed as its arguments. You can use convert() method, to convert one data type to another data type. Create and initialize the iterator and pass it into zip() method, it ...
Changed in version 3.7: Dictionary order is guaranteed to be insertion order. This behavior was an implementation detail of CPython from 3.6. # python 3.7.1 >>> d = {'one': 1, 'two': 2, 'three': 3, 'four': 4} >>> d
'成都市武侯区科华北路62号1栋101'}# 可以通过Python内置函数zip压缩两个序列并创建字典items1=dict(zip('ABCDE','12345'))print(items1)# {'A': '1', 'B': '2', 'C': '3', 'D': '4', 'E': '5'}items2=dict(zip('ABCDE',range(1,10)))print(items2)# {'A': 1, 'B': ...
在Python中,你可以使用zip方法将两个list组装成一个dict,其中一个list的值作为KEY,另外一个list的值作为VALUE: >>> given = ['John', 'Eric', 'Terry', 'Michael'] >>> family = ['Cleese', 'Idle', 'Gilliam', 'Palin'] >>> pythons = dict(zip(given, family)) >>> print pythons {'John...
#zip建立字典 print zip(['a','b'],[1,2]) #返回list d = dict(zip([1,2],['a','b'])) print d 输出为: [('a', 1), ('b', 2)] {1: 'a', 2: 'b'} #设置默认值 dict = {} dict.setdefault("a") print dict dict["a"] = "apple" dict.setdefault("a","default") pr...
