Now that you are about to write longer, more complex pieces of Python, it is a good time to talk about coding style. Most languages can be written (or more concise, formatted) in different styles; some are more readable than others. Making it easy for others to read your code is alway...

It is ideal for hiking. 注意,在 Python 中我们不像其他语言那样使用分号来结束语句。 格式方法可以与打印方法结合使用,用于在字符串中嵌入变量。它使用花括号作为变量的占位符,这些变量作为参数传递给方法。 让我们看一个简单的例子,我们使用格式方法打印变量。 代码: weight=4.5 name="Simi" print("The ...
