我如何能夠制作一個可以讀取檔案夾中所有 csv 檔案并動態為其分配變數名稱的 python 腳本。資料集的變數名稱將是 csv 檔案的名稱。folder_location例如，在指定的FTX_BTCUSD.csv分配的 csv 檔案將被命名FTX_BTCUSD為變數。Pandas 將用于讀取使用 .csv 檔案的 csv 檔案pd.read_csv()。我如何能夠修改下面的函式以獲得預期的輸出。
import pandas as pd
folder_location = 'C:\\Users\\local\\datasets'
def pandas_datasets():
data= pd.read_csv(**dataset location**, low_memory=False)
return data

uj5u.com熱心網友回復：
globals()盡管不建議這樣做，但您可以通過創建變數。使用帶有鍵作為檔案名的字典要好得多。
嘗試：
import os
data = dict()
for file in os.listdir(folder_location):
if file.endswith(".csv"):
data[file.replace(".csv","")] = pd.read_csv(os.path.join(folder_location, file))
如果您絕對必須使用檔案名創建動態變數，請改用以下內容：
import os
for file in os.listdir(folder_location):
if file.endswith(".csv"):
globals()[file.replace(".csv","")] = pd.read_csv(os.path.join(folder_location, file))
