代码开发环境：Eclipse
1.打印字符串：
print "Hello world!" myString = "Hello world!" print myString

3.读取用户输入
输入字符串：
user = raw_input('Enter login name: ') print "Your login name is: ", user
运行结果：
Enter login name: root Your login name is: root
输入数字：
num = raw_input('Now enter a number: ') print 'Doubling your number: %d' % (int(num) * 2)
运行结果：
Now enter a number: 1024
Doubling your number: 2048
注意：
需要利用内建函数int()将数值字符串转换成整数值，然后才可以对它进行数学运算。
