如何从 Dropbox Online 读取 csv 文件？

Question

How can I read a csv file from Dropbox Online (without downloading it to local machine)?

I installed and imported dropbox in Python, created an app and got a token from "https://www.dropbox.com/developers/apps". While I read some resources online, I am still fuzzy on how I move from here.

Answer 1

Line 149 on the example here provides a function that downloads a file and returns it as a byte string.

https://github.com/dropbox/dropbox-sdk-python/blob/main/example/updown.py

Then just parse the byte string, for example using pandas :

import pandas as pd
from example.updown import download   # import the download function from updown.py, or copy or replicate that function, I'm only providing pseudo code here

file_as_bytes = download(dbx, folder, subfolder, name)
df = pd.read_csv(file_as_bytes)
print(df)

Answer 2

Think as suggested here you can just read directly over the URL (but you need to change the arg from ?dl=0 to ?dl=1

eg

df = pd.read_csv("https://www.dropbox.com/s/asdfasdfasfasdf/movie_data.csv?dl=1")
