def fib(max): n, a, b = 0, 0, 1 while n < max: print(b) a, b = b, a + b n = n + 1 return 'done' 注意,赋值语句: a, b = b, a + b 相当于: t = (b, a + b) # t是一个tuple a = t[0] b = t[1]
一.三元运算 三元运算又称三目运算,是对简单的条件语句的简写,如: 简单条件处理: if 条件成立: val = 1 else: val = 2 改成三元运算 val = 1 if 条件成立 else 2 二.智能检测文件编码 用第三方模块chardet 首先要安装chardet模块 ,用pip命令进行安装 chardet的用法 import chardet f = open("staff_table.txt","rb") data =f.read() f.clos
