我有以下几点：

x = [1,2,3,4,5]
def foo(lbd:str, value):
    ret_val = eval(lbd, globals(), locals())
    print(ret_val)

在此调用中使用 'value' 变量成功：

>>> foo("[i for i in value]",x)
            
[1, 2, 3, 4, 5]

但是这个失败了：

>>> foo(r"any([x in value for x in {'',0,None,'0'}])", x)
            
Traceback (most recent call last):
  File "<pyshell#171>", line 1, in <module>
    foo(r"any([x in value for x in {'',0,None,'0'}])", x)
  File "<pyshell#165>", line 2, in foo
    ret_val = eval(lbd, globals(), locals())
