操作系统。重命名(旧的,新的)

这可以在Python文档中找到:http://docs.python.org/library/os.html

import shutil
import os

files = os.listdir("./pics/") 

for key in range(0, len(files)):
   print files[key]
   shutil.move("./pics/" + files[key],"./pics/img" + str(key) + ".jpeg")

这个应该可以了。python 3 +

import os

# Set the path
path = 'a\\b\\c'  
# save current working directory
saved_cwd = os.getcwd()
# change your cwd to the directory which contains files
os.chdir(path)
os.rename('a.txt', 'b.klm')
# moving back to the directory you were in 
os.chdir(saved_cwd)

如何修改目录中文件名的首字母。

import os
path = "/"

for file in os.listdir(path):
    os.rename(path + file, path + file.lower().capitalize())

then = os.listdir(path)
print(then)

操作系统。重命名(旧的,新的)

这可以在Python文档中找到:http://docs.python.org/library/os.html

import os
import re
from pathlib import Path

for f in os.listdir(training_data_dir2):
  for file in os.listdir( training_data_dir2 + '/' + f):
    oldfile= Path(training_data_dir2 + '/' + f + '/' + file)
    newfile = Path(training_data_dir2 + '/' + f + '/' + file[49:])
    p=oldfile
    p.rename(newfile)
