无法使用python shutil复制或移动文件

Question

import shutil
import os

source = os.listdir("report")
destination = "archieved"

for files in source:
    if files.endswith(".json"):
        shutil.copy(files, destination)

我的文件名为＆＃39; a.json＆＃39;在报告文件夹report/a.json内;但是，文件不会移动/复制到目标文件夹

控制台错误：

*** FileNotFoundError: [Errno 2] No such file or directory: 'a.json'

os.listdir()返回文件名而不是路径。在调用shutil.copy()之前，您需要从文件名构造路径。

import shutil
import os

source_directory_path = "report"
destination_directory_path = "archived"

for source_filename in os.listdir(source_directory_path):
    if source_filename.endswith(".json"):
        # construct path from filename
        source_file_path = os.path.join(source_directory_path, source_filename)

        shutil.copy(source_file_path, destination_directory_path)
