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

# script.py
current_file = os.path.abspath(os.path.dirname(__file__)) #older/folder2/scripts_folder

#csv_filename
csv_filename = os.path.join(current_file, '../data_folder/data.csv')

Answer 2

import pandas as pd
df = pd.read_csv('C:/data_folder/data.csv')

Answer 3

Keeping things tidy with f-strings:

import os
import pandas as pd

data_files = '../data_folder/'
csv_name = 'data.csv'

pd.read_csv(f"{data_files}{csv_name}")

Answer 4

This link here answers it. Reading file using relative path in python project

Basically using Path from pathlib you'll do the following in script.py

from pathlib import Path
path = Path(__file__).parent / "../data_folder/data.csv"
pd.read_csv(path)

Answer 5

With python or pandas when you use read_csv or pd.read_csv, both of them look into current working directory, by default where the python process have started. So you need to use os module to chdir() and take it from there.

import pandas as pd 
import os
print(os.getcwd())
os.chdir("D:/01Coding/Python/data_sets/myowndata")
print(os.getcwd())
df = pd.read_csv('data.csv',nrows=10)
print(df.head())
