问题描述

def success(self, input1: str = "", input2: str = "", input3: str = "") -> None:
E                               ^
E   SyntaxError: invalid syntax

不知道这里发生了什么..

No idea what is happening here..

代码:

 def success(self, input1: str = "", input2: str = "", input3: str = "") -> None:
        input1 = str(input1)
        input2 = str(input2)
        input3 = str(input3)
        print(Color.BOLD + Color.GREEN + " " + Color.CHECKMARK + " " + input1 + Color.END + " " + input2 + " " + input3)

推荐答案

您发布的函数是有效的 Python 3.7.类型提示被添加到 Python 3.5.0 版，你的代码发布应该适用于 3.5.0 以后的任何版本:

The function you posted is valid Python 3.7. Type hints were added to Python in version 3.5.0, the code you posted should work in any version from 3.5.0 onwards:

Python 3.7.0 (default, Aug 22 2018, 20:50:05) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def success(self, input1: str = "", input2: str = "", input3: str = "") -> None:
...         input1 = str(input1)
...         input2 = str(input2)
...         input3 = str(input3)
...         print(Color.BOLD + Color.GREEN + " " + Color.CHECKMARK + " " + input1 + 
Color.END + " " + input2 + " " + input3)
... 
>>> success
<function success at 0x7fb70e4c61e0>

我怀疑您使用的是不支持这些语言功能的旧版 python.

I suspect you are using an older python version that does not support these language features.
