2. Use zip() to Convert Two Lists to Dictionary Thezip()function in Python is used to combine two lists into a single list of tuples, where the first element of the tuple contains the elements of first list, the second element of the tuple contains the element from second list and pas...
{1: 'python', 2: 'c', 3: 'c++'} We have two lists: index and languages. They are first zipped and then converted into a dictionary. The zip() function takes iterables (can be zero or more), aggregates them in a tuple, and returns it. Likewise, dict() gives the dictionary. ...
如果L1和L2是包含键和对应值的列表对象,则可以使用以下列表推导式语法构建字典对象. >>>L1=['a','b','c','d']>>>L2=[1,2,3,4]>>>d={L1[k]:L2[k]forkinrange(len(L1))}>>>d{'a':1,'b':2,'c':3,'d':4} Python 更多Python相关文章,请阅读:Python 教程 ...
mylist=[("a",1),("b",2)] Bash 我们可以使用dict()函数将其转换为字典: mydict=dict(mylist)print(mydict) Python 输出结果为: {'a':1,'b':2} Bash 方法2:使用字典推导式 另一种将列表转换为字典的方法是使用字典推导式。字典推导式是一种简洁的语法形式,用来创建一个字典。使用字典推导式将列表...
{0:'a',1:'b',2:'c'} Copy 5. Using a list of keys method Converting a list to a dictionary can be done by using the list of key method. Create two lists, one for keys and one for values. Zip the two lists together using thezip()function to create a list of key-value pairs...
2. python 两个列表分别组成字典的键和值 (python two list serve as key and value for dictionary) https://stackoverflow.com/questions/209840/convert-two-lists-into-a-dictionary In [1]: layout_type = ['LTTextBox','LTFigure','LTImage','LTLine','LTRect'] ...
# Example 2: Convert to dictionary using a for loop mydict = {} for item in list_tuples: key = item[0] value = item[1] mydict[key] = value # Example 3: Convert a list of tuples to a dictionary # Using dictionary comprehension ...
"two": 2 } my_dictionary["three"] = 3 print(my_dictionary)Copy The code shows the updated dictionary contents after adding a new item. Method 2: Using update() Theupdate()method adds a new element to an existing dictionary: dictionary_name.update({key:value})Copy ...
If you need to destructively iterate through a dictionary in Python, then .popitem() can do the trick for you: Python >>> likes = {"color": "blue", "fruit": "apple", "pet": "dog"} >>> while True: ... try: ... print(f"Dictionary length: {len(likes)}") ... item ...
