Python 错误 FileNotFoundError: [Errno 2] 没有这样的文件或目录：

Question

Im trying to run my code with this but keep running into a file not found error.

files = [i for i in os.listdir('C:/Users/me/Desktop/python data')]
for filename in files:    
    data = pandas.read_excel(str(filename))

I've tried looking around but cant seem to understand.

Running print(os.getcwd()) does find the file in the folder but i still get the error message

Answer 1

You need to concatenate the path and the filename returned from os.listdir :

PATH = 'C:/Users/me/Desktop/python data'
files = [os.path.join(PATH, i) for i in os.listdir(PATH)]
for filename in files:
    data = pandas.read_excel(str(filename))

Further recommendations:

1. You can use pathlib 's .glob to get the full path without using os.path.join .
2. Also, if you use read_excel , please consider filtering by xls/xlsx files:

Code example:

import pathlib


path = pathlib.Path('C:/Users/me/Desktop/python data')
excel_filter = "*.xls*"
for filename in path.glob(excel_filter):
    print(filename)
