we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...

This makes them ideal for short, one-off tasks. Inline: Lambda functions can be defined inline, meaning they can be defined within the same line of code as the function call. This makes them even more concise and easier to read. Single expression: Lambda functions can only contain a ...
game.display.update() objectClock.tick(20) #if you remove following line of code, IDLE will hang at exit game.quit() 上述代码由许多代码片段组成:初始化游戏变量,然后创建游戏模型。在步骤3中,我们创建了一些简单的逻辑来控制游戏的动画。我们在步骤3中构建了两个代码模型,使我们的游戏对用户进行交互(...

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 functions helps to keep the code clean and improve readability. It also makes the program reusable, which prevents repeating ...
