Whenever we need to write text into a file, we have to open the file in one of the specified access modes. We can open the file basically to read, write or append and sometimes to do multiple operations on a single file. To write the contents into a file, we have to open the file...
² SOLID 是 Robert C. Martin 关于面向对象设计的五个原则的首字母缩写:单一职责、开放封闭、里氏替换、接口隔离和依赖反转。参见 Samuel Oloruntoba 的文章“S.O.L.I.D: The First 5 Principles of Object-Oriented Design”。 第一部分:构建支持领域建模的架构 原文:Part 1: Building an Architecture to S...

In this case, we open the file, loop through and store it in memory to the lines variable, then close it. The for loop here uses a list comprehension, each line is a line as interpreted by the open() function, which in this case is a newline (\n). This block of code also ...
