我想重命名Google驱动器文件夹中的100个文件。所以我写了下面的代码：
from google.colab import drive
drive.mount('/content/drive')
import os
for index in range(801,901):
src=f'/content/drive/My Drive/ai-projectroll-17198,17108/.div2k/images/DIV2K_valid_LR_bicubic/X4/{index:04}X4.png'
dst=f'/content/drive/My Drive/ai-projectroll-17198,17108/.div2k/images/DIV2K_valid_LR_bicubic/x4/{index+200:04}X4.png'
os.rename(src,dst)
但是出现以下错误：
---------------------------------------------------------------------------
FileNotFoundError Traceback (most recent call last)
<ipython-input-24-313e46a40c1b> in <module>()
4 dst=f'/content/drive/My Drive/ai-projectroll-17198,17108/.div2k/images/DIV2K_valid_LR_bicubic/x4/{index+200:04}X4.png'
5 #print(dst)
----> 6 os.rename(src,dst)
FileNotFoundError: [Errno 2] No such file or directory: '/content/drive/My Drive/ai-projectroll-17198,17108/.div2k/images/DIV2K_valid_LR_bicubic/X4/0801X4.png' -> '/content/drive/My Drive/ai-projectroll-17198,17108/.div2k/images/DIV2K_valid_LR_bicubic/x4/1001X4.png'
我如何摆脱它？对于另一个文件夹，它工作正常。
答案 0 :(得分：0)
请查看错误“ FileNotFoundError”，该文件不存在。
仔细检查路径
我不知道colab / Google驱动器BUT的结构
尝试（路径中带有后缀“。”）：
也
这是输出...我注意到我在第一行没有失败。检查您的路径。

您可以尝试遍历文件夹中的每个png文件。
import os
for root, dirs, files in os.walk("/content/drive/My Drive/ai-projectroll-17198,17108/.div2k/images/DIV2K_valid_LR_bicubic/X4"):
for file in files:
if file.endswith(".png"): # add extra conditional logic here i.e if contains [801-901] etc etc
print(file) # get path
print(os.path.basename(file)) # get file name
os.rename(file, 'new file name') # rename the file
