Python 程序的运行时间需要 0.1 秒，慢了 100 倍，但由于 网络更慢，需要等待 1 秒，你想，用户能感觉到 1.001 秒和 1.1 秒的区 别吗？这就好比 F1 赛车和普通的出租车在北京三环路上行驶的道理一 样，虽然 F1 赛车理论时速高达 400 公里，但由于三环路堵车的时速只 有 20 公里，因此，作为乘客，你感觉的时速永远是 20 公里。 Python3 基础教程【完整版】 可以处理任意大小的整数，当然包括负整数，在程序中的表示方 法和数学上的写法一模一样，例如：1，100，-8080，0，等等。 计算机由于使用二进制，所以，有时候用十六进制表示整数比较方便， 十六进制用 0x 前缀和 0-9，a-f 表示，例如：0xff00，0xa5b4c3d2，等等。 浮点数 浮点数也就是小数，之所以称为浮点数，是因为按照科学记数法表示时， 一个浮点数的小数点位置是可变的，比如，1.23x109 和 42/531 >>> 10 % 3 1 无论整数做//除法还是取余数，结果永远是整数，所以，整数运算结果 永远是精确的。 练习 请打印出以下变量的值： n = 123 f = 456.789 s1 = 'Hello, world' s2 = 'Hello, \'Adam\'' s3 = r'Hello, "Bart"' s4 = r'''Hello, Lisa
