Question

我试图通过从文本文件“input.txt”中读取文件名来将几个文件从一个文件夹复制到另一个文件夹。我做错了什么？先感谢您。

import shutil
import os
f = open('input.txt','r')
src=r'C:\Users\abhishekcho\Desktop\Self\folder1'
dst=r'C:\Users\abhishekcho\Desktop\Self\folder2'

for i in range(4):
    file_name = f.readline()
    source = os.path.join(src,file_name)
    shutil.copy2(source,dst)

---

输出：

PS C:\Users\abhishekcho\Desktop\Self> &
C:/Users/abhishekcho/AppData/Local/Programs/Python/Python37-32/python.exe
c:/Users/abhishekcho/Desktop/Self/test.py Traceback (most recent call

好像尾随换行符 \n 包含在您的路径中并导致错误。你可以删除它rstrip()

import shutil
import os
f = open('input.txt','r')
src=r'C:\Users\abhishekcho\Desktop\Self\folder1'
dst=r'C:\Users\abhishekcho\Desktop\Self\folder2'

for i in range(4):
    file_name = f.readline().rstrip()
    source = os.path.join(src,file_name)
    shutil.copy2(source,dst)
