foriteminmyDictionary: print(item) 执行和输出: 打印出了所有的键元素。 3.1. 循环遍历字典的键和值 要拿到相关的值的话,你可以使用拿到的键去获取对应的值。 #Loopthrough keysandvaluesofDictionary forkeyinmyDictionary: print(key, myDictionary[key], sep=':') ...
Iterating Through Dictionary Keys: The .keys() Method Walking Through Dictionary Values: The .values() Method Changing Dictionary Values During Iteration Safely Removing Items From a Dictionary During Iteration Iterating Through Dictionaries: for Loop Examples Filtering Items by Their Value Running Calcul...
The second loop is more explicit and readable, but it can be less efficient than the first loop because of the additional method call. Note that in both loops, you can access the dictionary values as well: Python >>> for student in students: ... print(student, "->", students[...
myDictionary[newKey] = newValue 其中myDictionary 就是我们要添加键值对 newKey:newValue 的现有索引。 2.1. 添加多个元素到字典 在本示例中,我们将要添加多个元素到字典中去。 # create and initialize a dictionary myDictionary = { 'a' : '65', ...
In contrast, the Python while loop repeats as long as a certain condition is true. This tutorial describes how to use both types of loops and explains how to use Python for common scenarios like looping through a dictionary. An Introduction to Python for and while Loops The Python for ...
Python provides various ways to loop through the items or elements of a list. By using for loop syntax you can iterate any sequence objects (string,list,tuple,set, range, ordictionary(dict)). Alistcontains a collection of values so, we can iterate each value present in the list usingPytho...
While iterating through a dictionary, you can access its keys and values at the same time. You can do this in two ways. The first method is to iterate through the dictionary and access the values using thedict[key]method. Then print each key-value pair within the loop: for key in my...
