How to open my files in data_folder with pandas using relative path?

Question

I\'m working with pandas and need to read some csv files, the structure is something like this:

folder/folder2/scripts_folder/script.py

folder/fol

Answer 1

For non-Windows users:

import pandas as pd
import os

os.chdir("../data_folder")
df = pd.read_csv("data.csv")

For Windows users:

import pandas as pd

df = pd.read_csv(r"C:\data_folder\data.csv")

The prefix r in location above saves time when giving the location to the pandas Dataframe.
