映射list   Dictionary 是用{}. list 是一那个[]. turple是用() 当你定义过dictionary后,你可以使用d.keys(), d.values(),d.items()将定义后的时候分别显示出来 当然可以将list里的值加减乘除,也可以如一般的定义直接重新复制这个list. 链接与分割字符串的 li=";", join(li) 则显示的就是 分隔符为;的数 如果使用li=li.split(";")则将刚刚;的分隔符删除,而split里也可定义域,如li.split(";",1)   自省 <---这是啥 之前在使用的时候发觉有些书本上的模块不能调用,很多是py脚本定义过的函数。 下载该脚本s,然后上传至指定位置。 >>>import sys >>>sys.path >>>sys.path.append("绝对位置")然后就能调用这些脚本和参数了。 删除 >>>sys.path.pop() 定义一个参数是 def info(test, test1=10.test2=12): info是函数名,test是必备参数,因为没有定义值,test1和test2是可选参数,定义了初始值   以上是外部函数的调用,下面转到内部函数 内部函数有type,str,dir及其他   ---type 返回任意字符的类型,模块也可以。types模块 >>> type(1) <type 'int'> >>> li=[] >>> type(li) <type 'list'> >>> import odbchelper >>> type(odbchelper) <type 'module'> >>> type(sys) <type 'module'> >>> import types ...

methodList = [method for method in dir(object) if callable(getattr(object, method))] ###插一句, ifconfig pcn0 unplumb 去禁solaris的网卡plumb起网卡   and, or  已经and-or一起用。 and 两者为真,print第二个数,一个为假一个为真返回假,三者为真返回最后一个真。 or 两个为真,返回第一个, 一个为假一个为真返回真,三者为假返回最后一个假   lambda可快速定义最小值函数   g = lambda x:x*2 g(3) 6 (lambda x:x*2)(3)   doc string print getattr(object,mothod).__doc__   ljust ljust 用空格填充字符串以符合指定的长度。info 函数使用它生成了两列输出并将所有在第二列的 doc string 纵向对齐。 如果小于的话不会从中截断   -----面向对象 首先导入,你可以选择import module or from module import module 如果你要经常访问模块的属性和方法,且不想一遍又一遍地敲入模块名,使用 from module import。 如果你想要有选择地导入某些属性和方法,而不想要其它的,使用 from module import。 如果模块包含的属性和方法与你的某个模块同名,你必须使用 import module 来避免名字冲突   -----类的定义 class Lofs    pass   这个类的名字是 Loaf,它没有从其它类继承。 类名通常是第一个字母大写,如:EachWordLikeThis,但这只是一个习惯,不是一个必要条件。   这个类没有定义任何方法或属性,但是从语法上,需要在定义中有些东西,所以你使用 pass。这是一个 Python 保留字,仅仅表示 “向前走,不要往这看”。它是一条什么都不做的语句,当你删空函数或类时,它是一个很好的占位符。   你可能猜...
