Question

如何从文件夹中获取所有文件并使用python存储它？此代码查找文件

# list of dir

list_of_dir = os.listdir(dir_loc)
print(list_of_dir)

我如何存储这些文件？文件类型可以是jpeg，png，txt，csv。我需要将所有文件上传到数据库（mongodb）

Answer 1

我们列出当前目录并打印内容您可以对读取文件执行其他操作，即操作

import os

dir_loc = os.getcwd()
list_of_dir = os.listdir(dir_loc)


for file in list_of_dir:
    with open(file, 'rb') as f:
        temp_file = f.read()
    # Do somethin with the file, it's currently stored in a variable
    print(temp_file) # I used print

Pymongo ：

import os
import pymongo
import gridfs

dir_loc = os.getcwd()
list_of_dir = os.listdir(dir_loc)

# Pymongo
connection = pymongo.Connection("localhost", 27017)
db = connection.yourdatabase

# Create a GridFS object using a reference to the database in which to
# store the file(s).

gridFs = gridfs.GridFS(db)


for file in list_of_dir:
    with open(file, 'rb') as f:
        file_id = gridFs.put(f.read(), filename="my_file_name")

Answer 2

您只需使用以下代码将其存储到txt文件：

with open("somefile.txt", 'w') as f:
    f.write(str().join([filename+'\n' for filename in filenames]))
