我如何获得Python函数的源代码？ 10个答案

我希望能够打印一个lambda函数的定义代码。

例如，如果我通过lambda语法定义了这个函数：

>>>myfunction = lambda x: x==2 >>>print_code(myfunction)

我想要得到这个输出：

x==2

How can I get the source code of a Python function? 13 answers

I'd like to be able to print the definition code of a lambda function.

Example if I define this function through the lambda syntax:

>>>myfunction = lambda x: x==2 >>>print_code(myfunction)

I'd like to get this output:

x==2

只要您将代码保存到源文件，您就可以使用inspect模块检索对象的源代码。

例如：打开编辑器类型：

myfunction = lambda x: x==2

保存为lamtest.py

打开shell类型的python来获得交互式python类型如下：

>>>from lamtest import myfunc >>>import inspect >>>inspect.getsource(myfunc)

结果：

'myfunc = lambda x: x==2\n'

As long as you save your code to a source file you can retrieve the source code of an object using the inspect module.

example: open editor type:

myfunction = lambda x: x==2

save as lamtest.py

open shell type python to get to interactive python type the following:

>>>from lamtest import myfunc >>>import inspect >>>inspect.getsource(myfunc)

the result:

'myfunc = lambda x: x==2\n'
