(Python小白）Juoyter Notebook里"str"函数显示不可调用怎么办

Question

源代码

num1 = 8
str3 = str(num1)
type(str3)

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-44-d1a6e2ae0296> in <module>
      1 num1 = 8
----> 2 str3 = str(num1)
      3 type(str3)

TypeError: 'str' object is not callable

Answer 1

你的代码没问题的，你是不是自定义了一个str变量，把内置的str函数覆盖了
