Python global 语句的作用 在编写程序的时候,如果想要改变(重新赋值)函数外部的变量,并且这个变量会作用于许多函数中,就需要告诉 Python 程序这个变量的作用域是全局变量,global 语句可以实现定义全局变量的作用。 lambda 匿名函数好处 精简代码,lambda省去了定义函数,map 省去了写 for 循环过程: str_1 = ["中国"...

We can create a function that writes the Fibonacci series to an arbitrary boundary:先举一个例子，我们可以创建一个函数，将斐波那契数列写入任意边界。如下：>>> >>> def fib(n): # write Fibonacci series up to n 创建斐波那契数列到n... """Print a Fibonacci series up to n.创建斐波那契...
