您如何以字符串形式读取lambda函数? [英] How do you read a lambda function as a string?

问题描述

创建完一个lambda函数后，我想阅读它.

I'd like to read a lambda function I created as a string, after I created it.

例如，

func = lambda num1,num2: num1 + num2

我想将func读为:

'lambda num1,num2: num1 + num2'

有没有一种方法可以做到这一点，甚至可以读取lambda函数的任何部分?

Is there a way to accomplish this or even read any part of the lambda function?

推荐答案

编辑:由于我误解了问题，因此更改了我的第一个答案.这个答案是从许多其他用途中借用的，但是我已经完成了代码，仅显示所需字符串的一部分.

Edit: Changed my first answer as I misunderstood the question. This answer is borrowed from a number of other uses, however I have completed the code to only display the part of the string that you want.

import inspect

func = lambda num1,num2: num1 + num2
funcString = str(inspect.getsourcelines(func)[0])
funcString = funcString.strip("['\\n']").split(" = ")[1]
print funcString

输出以下字符串:

lambda num1,num2: num1 + num2
