python3下tomorow模块 @thread报语法错误def async(n, base_type, timeout=None): ^ SyntaxError: invalid syntax---解决方法

遇见问题：python使用tomorrow实现多线程，tomorrow模块的源代码报语法错误？

这是报错信息：
Traceback (most recent call last):
  File "C:/programmer/boyuncar900_v1/main.py", line 5, in <module>
    from tomorrow import threads
  File "C:programmerpythonlibsite-packages omorrow_init_.py", line 1, in <module>
    from .tomorrow import threads
  File "C:programmerpythonlibsite-packages omorrow omorrow.py", line 20
    def async(n, base_type, timeout=None):
            ^
SyntaxError: invalid syntax

解决办法：async是python关键字，源代码换个函数名，比如async_tm。

from tomorrow import threads


def add_case(case_path=casepath, rule="test*.py"):

    pass

@threads(5)
def run_case(all_case, report_path=reportpath, nth=0):

    '''执行所有的用例, 并把结果写入测试报告'''

    pass

        elif isinstance(n, base_type):
            pool = n

                timeout=timeout
            )
        return wrapped
    return decorator

    return async_mc(n, ThreadPoolExecutor, timeout)
