老师，我运行的到的路径拼接符是相反的

def get_project_path():
    """
    获取项目绝对路径
    :return:
    """
    project_name = "trading_system_autotest"
    # 获取当前文件的所在目录的绝对路径
    file_path = os.path.dirname(__file__)
    # print(file_path)
    # # 在绝对路径中找到项目名称的下标位置
    # print(file_path.find(project_name))
    # # 找到项目所在目录的绝对路径+项目名称的长度=项目的绝对路径
    print(file_path[: file_path.find(project_name)+len(project_name)])
    return file_path[:file_path.find("project_name")+len(project_name)]


def sep(path, add_sep_before=False, add_sep_after=False):
    all_path = os.sep.join(path)
    # print(all_path)
    if add_sep_before:
        all_path = os.sep + all_path
    if add_sep_after:
        all_path = all_path + os.sep
    # print(all_path)
    return all_path


if __name__ == '__main__':
    # pass
    # get_project_path()
    print(sep(["config", "environment.yaml"], add_sep_before=True))
    print(get_project_path() + sep(["config", "environment.yaml"], add_sep_before=True))

运行的结果是

\config\environment.yaml
D:/me/code/trading_system_autotest
D:/me/code/trading_sys\config\environment.yaml  # 就这个
