请注意,print指令是缩进的:这意味着它属于由if子句定义的作用域。执行这段代码会产生: $ python conditional.1.py I need to call my manager! 由于late是True,print语句被执行了。让我们扩展一下这个例子: # conditional.2.pylate =Falseiflate:print('I need to call my manager!')#1else:print('no nee...

参数lines:是一个由一个或多个元组构成的列表,元组有两个整型成员START和END表示格式化的范围。常被用于第三方工具的代码中,用于重新格式化一小块代码而不是整个文件的时候。 参数print_diff:是布尔类型,返回格式化结果与需要格式化的文本的不同,而不是返回格式化的结果 ...
point1.move(3,4)print(point1.calculate_distance(point2))print(point1.calculate_distance(point1)) 结尾处的print语句给出了以下输出: 5.04.472135954999580.0 这里发生了很多事情。这个类现在有三个方法。move方法接受两个参数x和y,并在self对象上设置值,就像前面示例中的旧reset方法一样。旧的reset方法现在调...
It’s important to note that f-strings and themethod also support the conversion types listed above. For details on this topic, check out theConverting Between Type Representationssection in thePython’s Format Mini-Language for Tidy Stringstutorial. ...
In the other examples, you get strings consisting of the object’s literals between quotes, which provide user-friendly representations of the objects. At first glance, these results may not seem useful. However, there are use cases where you need to use str(). For example, say that you ...
The if and else lines are Python statements that check whether a condition (here, the value of disaster) is True. Remember, print() is Python’s built-in function to print things, normally to your screen. Note If you’ve programmed in other languages, note that you don’t need parenthes...
