我大约需要重命名150.000个图像文件。这些存储在Unix系统上，我列出文件，使用regex查找要重命名的位并进行重命名。查看输出，发现文件已被删除。如果仅用打印语句替换os.rename，则所有文件都会存在并重命名。我尝试从Jupiter笔记本远程运行代码，并使用可执行脚本在本地运行代码，其行为相同：随机删除某些文件。有人有解释吗？ 这是代码
import os as os
import re as re
pattern = re.compile('(.*_.*Z0)(\d)(C0\d.tif)')
for file in os.listdir('.'):
if file.startswith("08") and not file.endswith("C04.tif"):
res = re.search(pattern, file)
zPlane = str(int(res.group(2))-2)
os.rename(file, res.group(1)+zPlane+res.group(3))
和一些文件名

将“一些文件名”存储在名为f.txt的文件中，使用：
with open("f.txt","r") as r:
files = set((x.strip() for x in r.readlines()))
import re as re
results = {}
pattern = re.compile(r'(.*_.*Z0)(\d)(C0\d.tif)')
for file in files:
if file.startswith("08") and not file.endswith("C04.tif"):
res = re.search(pattern, file)
zPlane = str(int(res.group(2))-2)
# overwriting existing file
newname = res.group(1)+zPlane+res.group(3)
if newname in files:
print(newname," overwrites existing file")
# check if two files get renamed into the same one
keyy = results.setdefault(newname,[])
keyy.append( file )
# this outputs nothing
for k in results:
if len(results[k])>1:
print(k,results[k])
您正在通过重命名覆盖现有文件。我从一个文本文件中获取了它们。
将文件A重命名为B（已经存在），然后在处理文件B时将其重命名为C。这样看起来好像文件已被删除。
