本文通过一个具体的Python脚本示例介绍了如何在程序中打印文本、进行简单的数学运算以及定义并调用函数来完成特定任务，如计算不同起点的豆子数量。

print "Let's practice everything."
print 'You\'d need to know \'bout escapes with \\ that do \n newlines and \t tabs.'

poem = """
\tThe lovely world
with logic so firmly planted
cannot discern \n the needs of love
nor comprehend passion from intuition
and requires an explanation
\n\t\twhere there is none.
"""

print "--------------"
print poem
print "--------------"


five = 10 - 2 + 3 - 6
print "This should be five: %s" % five  #此处直接显示5而不是上面的表达式/所以什么时候字符串

def secret_formula(started):
    jelly_beans = started * 500
    jars = jelly_beans / 1000
    crates = jars / 100
    return jelly_beans, jars, crates


start_point = 10000
beans, jars, crates = secret_formula(start_point)  #函数中的变量都是临时的，所以在脚本中可以使用任何名字

print "With a starting point of: %d" % start_point
print "We'd have %d beans, %d jars, and %d crates." % (beans, jars, crates)

start_point = start_point / 10

print "We can also do that this way:"
print "We'd have %d beans, %d jars, and %d crates." % secret_formula(start_point)
