一、Python input()函数:获取用户输入的字符串 Python3.x 中 input() 函数接受一个标准输入数据,返回为 string 类型。 Python2.x 中 input() 相等于eval(raw_input(prompt)),用来获取控制台的输入。 raw_input() 将所有输入作为字符串看待,返回字符串类型。而 input() 在对待纯数字输入时具有自己的特性,它...
Python 编程中 while 语句用于循环执行程序,即在某条件下,循环执行某段程序,以处理需要重复处理的相同任务。其基本形式为: while 判断条件(condition): 执行语句(statements)…… 执行语句可以是单个语句或语句块。判断条件可以是任何表达式,任何非零、或非空(null)的值均为true。 当判断条件假 false 时,循环结束。
