问题描述
是否有可能获得传递给函数的变量的原始变量名?例如
Is it possible to get the original variable name of a variable passed to a function? E.g.
foobar = "foo"
def func(var):
print var.origname
因此:
So that:
func(foobar)
返回:
>> foobar
编辑:
所有我试图做的功能都是:
All I was trying to do was make a function like:
def log(soup):
f = open(varname+'.html', 'w')
print >>f, soup.prettify()
f.close()
..并让该函数根据传递给它的变量的名称生成文件名。
.. and have the function generate the filename from the name of the variable passed to it.
我想如果这是不可能的,我只需要将变量和变量的名称作为一个字符串传递给每一个。
I suppose if it's not possible I'll just have to pass the variable and the variable's name as a string each time.
推荐答案
你不能。它在被传递给函数之前被评估。您只需将其作为字符串传递即可。
You can't. It's evaluated before being passed to the function. All you can do is pass it as a string.
