__file__
在ide中獲取的是絕對路徑，在終端啟動時，啟動位置是本模組，則為相對路徑，由外部模組呼叫則獲取的是未經解析的絕對路徑。
sys.path[0]
忠實的表示啟動的檔案所在的路徑
os.getcwd()
獲取的是工作空間的路徑。ide中可以設定working directory，終端啟動時則是指你cd到的那個路徑下。
os.path.abspath(os.path.split(os.path.abspath(os.path.realpath(__file__)))[0] + 「/…/」)
此方法是我寫的獲取專案絕對路徑的工具方法。注意此檔案的位置固定為專案的util資料夾下。
補充：sys.argv
是呼叫指令碼時使用的路徑，list格式。是呼叫python命令的時候的第乙個引數。
如，在ide啟動時，ide預設配置的引數如圖
['/home/zmate/tzzs/mytz/development/test_start.py']:~/tzzs/mytz/development$ python test_start.py
['test_start.py']
:~/tzzs/mytz$ python development/test_start.py
['development/test_start.py']
