centos和pycharm中取绝对路径的差别

import os
import sys
project_path = os.path.dirname(os.path.dirname(__file__))
sys.path.append(project_path)   #D:/sylar/s15/my_project
from core import main

if __name__ == ‘__main__‘:
    main.home()

import os
import sys
start_path=os.path.abspath(‘start.py‘)              #取到start.py的绝对路径
bin_path=os.path.dirname(start_path)                #连续向上翻两次
project_path=os.path.dirname(bin_path)              #

sys.path.append(project_path)
print("hello")
print(sys.path)
print(os.path.abspath(project_path))
