一、Python之禅(The Zen of Python) The Zen of Python是Python语言的指导原则,遵循这些基本原则,你就可以像个Pythonista一样编程。具体内容你可以在Python命令行输入import this看到: The Zen of Python, by Tim Peters Beautiful is better than ugly. # 优美胜于丑陋(Python以编写优美的代码为目标) Explicit i...
Python dictionaries, more precisely, are a collection of object pairs: Image Source: Edlitera The item being translated is called thekeyand the translation is thevalue. You can rephrase this to say that a dictionary is a collection ofkey-value pairs. ...
index = [1, 2, 3] languages = ['python', 'c', 'c++'] dictionary = {k: v for k, v in zip(index, languages)} print(dictionary) Run Code Output {1: 'python', 2: 'c', 3: 'c++'} This example is similar to Example 1; the only difference is that list comprehension is bei...

A key aspect to be aware about regarding dictionaries is that they are not sequences, and therefore do not maintain any type of left-right order. 这意味着,如果在字典上循环,Key:Value对将以任意顺序迭代。 This means that if you’re looping over a dictionary,the Key:Value pairs will be iter...
The Python language provides functions as a method to bundle related lines of code that complete particular assignments. Functions allow us to conserve programming code from duplication by storing it as reusable blocks for later use. When working on a large program, breaking it into smaller function...

Exceptions are a way to break the normal flow of a program. They are most often used to indicate that an error has occurred, though exceptions are also used for other "exceptional" cases, such as the StopIteration exception that powers Python's for loops. Exceptions are used by "raising" ...
