import os
os.getcwd()
print(os.getcwd())

train = pd.read_csv('F:\\pythonProject3\\data\\data\\train.csv')

print(train)

train = pd.read_csv('..\\train.csv')

F:\PythonProject3\data\data

import os
path1=os.path.abspath('.') #表示当前所处的文件夹的绝对路径
print("path1@@@@@",path1)
path2=os.path.abspath('..') ## 表示当前所处的文件夹上一级文件夹的绝对路径
print("path2@@@@@",path2)

import pandas as pd
import numpy as np
import os
os.getcwd()
# F:\\pythonProject3\\data\\data\\train.csv
# dataset_path = '..'
train = pd.read_csv('..\\train.csv')
path1=os.path.abspath('.')
print("path1@@@@@",path1)
path2=os.path.abspath('..')
print("path2@@@@@",path2)
