Python項目模塊找不到路徑問題

此篇僅作為工作是遇到問題的記錄，不進行任何闡述

工作問題：
模塊無法正確找到路徑，也就是sys.path里面沒有當前模塊路徑，所以導致導包出錯，索性寫個小函數，將當前項目的所有文件夾都加入sys.path模塊，一勞永逸

添加到sys.path

rootpath = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
sys.path.extend([rootpath, ])

from libs.find_path import extend_path

syspath = sys.path
sys.path.extend(extend_path([rootpath, ]))
sys.path.extend(syspath)

extend_path函數

import os

PATHList = []
DirFlag = 1


def extend_path(tlist):
    """
    尋找路徑函數，解決單獨模塊找不到路徑問題
    :param tlist:  -> list of path
    :return:  -> if has dir then return dir list; else return final path list
    """
    global PATHList
    global DirFlag
    PATHList += tlist
    if DirFlag == 0:
        return PATHList
    ttlist = []
    DirFlag = 0
    for i in tlist:
        for data in os.listdir(i):
            tpath = os.path.join(i, data)
            if os.path.isdir(tpath) and '__pycache__' not in tpath and 'migrations' not in tpath:
                ttlist.append(tpath)
                DirFlag = 1
    return extend_path(ttlist)
