问题描述
||
以
operator.add
为例:
>>>import operator as op
>>>op.add(1,2) #means 1 + 2
3
>>>op.add.__name__
\'add\'
我想要某种:
>>>op.add.math_str
\"+\"
我可以获取所有那些数学字符串\"+\",\"-\",\">\"...
模块operator
支持的运行时吗?
编辑:
>>> [eval(x) for x in [\".\".join((\"op\",x,\"__doc__\")) for x in dir(op)]]
[\'abs(a) -- Same as abs(a).\',\'add(a,b) -- Same as a + b.\',\'and_(a,b) -- Same as a & b.\',\'concat(a,b) -- Same as a + b,for a and b sequences.\',\'contains(a,b) -- Same as b in a (note reversed operands).\',\'delitem(a,b) -- Same as del a[b].\',\'delslice(a,b,c) -- Same as del a[b:c].\',\'div(a,b) -- Same as a / b when __future__.division is not in effect.\',\'str(object) -> string\\n\\nReturn a nice string representation of the object.\\nIf the argument is a string,the return value is the same object.\',
上面的代码可以列出大多数运算符字符串,这意味着我可以使用re模块列出字符串?
谢谢!
