在Python中一个脚本(Script)是一个将要被当做主模块(main)执行的python文件。模块(Module)是一个以.py结尾的python文件,在文件中我们定义了函数、类,准备以后重用这些代码块。Python中模块的名字,就是以.py为后缀的文件的文件名,例如fibo.py,那么模块名就是fibo。__name__变量保存了引用的模块的名字,当模块被当...

JSON (JavaScript Object Notation) 是一种轻量级的数据交换格式。它基于ECMAScript的一个子集。 JSON和Python内置的数据类型对应如下: Python3 中可以使用 json 模块来对 JSON 数据进行编解码,它包含了四个函数: json.dumps(x) 把python的(x)原对象转换成json字符串的对象,主要用来写入文件。 json.loads(f) 把j...
From this point on, the rest of the script is the same. We begin by importing only the OptionParser class from our optparse module. We create a usage statement we can give to our parser, and then we define the parser and pass the statement as a usage option. We could pass this direc...
This script is friendly to already-configured path settings, and serves to demo platform-independent directory path processing. Python programs can always be started under the Windows port by clicking (or spawning a 'start' DOS command), but many book examples require the module search path too ...
frommodule.xx.xximport* 导入模块其实就是告诉Python解释器去解释那个py文件 导入一个py文件,解释器解释该py文件 导入一个包,解释器解释该包下的 __init__.py 文件 【py2.7】 那么问题来了,导入模块时是根据那个路径作为基准来进行的呢?即:sys.path

如果你退出python解释器然后重新进入,那么你之前定义的函数或者变量都将丢失,因此我们通常将程序写到文件中以便永久保存下来,需要时就通过python test.py方式去执行,此时test.py被称为脚本script。 随着程序的发展,功能越来越多,为了方便管理,我们通常将程序分成一个个的文件,这样做程序的结构更清晰,方便管理。这时我们不...
