<>一、实验目的
1、熟悉 Python 程序的运行环境与运行方式。
2、掌握 Python 的基本数据类型。
3、掌握 Python 的算术运算规则及表达式的书写方法。
<>二、实验内容
*
分别启动命令行的形式和图形用户界面形式的 Python 解释器，在命令和程序两种方式下执行下列的语句：
命令行：用户图形界面：
*
先导入 math 模块，再查看该模块的帮助信息，具体语句如下：
根据语句执行的结果，写出 math 模块包含的函数，并说明 log()，log10()，
log1p()，log2()等函数的作用以及它们的区别。
*
在 Python 提示符下，输入以下语句，语句执行结果说明了什么？
说明：赋值运算符，进行的地址值的赋值。
*
求下列表达式的值
*
、已知 x=12，y=10^-5，求下列表达式的值.
*
计算并输出π^2.请补充程序，并上机运行。
*
先执行下列语句
(1)
(2)range() 函数可创建一个整数列表，一般用在 for 循环中。
函数原型：range(start, stop[, step])
start: 计数从 start 开始。默认是从 0 开始。例如range（5）等价于range（0， 5）;
stop: 计数到 stop 结束，但不包括 stop。例如：range（0， 5） 是[0, 1, 2, 3, 4]没有5
step：步长，默认为1。例如：range（0， 5） 等价于 range(0, 5, 1)
(3)
*
编写一个 Python 程序，使其运行后输出“Hello, Python Program”
print("Hello, Python Program");
