The simplest Python stack implementation uses the built-in list type. Its simplicity comes from the fact that it is built in and frequently used. In the example below, instead of the push() function, you use the append function to add new items at the end of the stack. The pop function...

We need to define the function before calling it to fix this error. Avoid Using Misspelled Variables or Function Names in Python Another reason to get this error is when a user is making mistakes in defining the correct spelling of a function; that is why the user is getting this type of...

匿名函数/ Anonymous Function 匿名函数是一种不需要绑定函数名的函数 (i.e. functions that are not bound to a name)。匿名函数通过 lambda 表达式进行构建。常用于快速建立起一个(一次性的)函数。 Note:lambda 是 Python 的一个表达式/关键字,类似 return,并非一个函数,而是能够生成匿名函数。
