Question

如何重命名以下文件：

abc_2000.jpg
abc_2001.jpg
abc_2004.jpg
abc_2007.jpg

进入以下几个：

year_2000.jpg
year_2001.jpg
year_2004.jpg
year_2007.jpg

相关代码是：

import os
import glob
files = glob.glob('abc*.jpg')
for file in files:
    os.rename(file, '{}.txt'.format(???))

Answer 1

import os
import glob
files = glob.glob('year*.jpg')
for file in files:
    os.rename(file, 'year_{}'.format(file.split('_')[1]))

一行可以分解为：

for file in files:
    parts = file.split('_') #[abc, 2000.jpg]
    new_name = 'year_{}'.format(parts[1]) #year_2000.jpg
    os.rename(file, new_name)

Answer 2

因为我今天做了类似的事情：

#!/usr/bin/env python

import os
import sys
import re

if __name__ == "__main__":
    _, indir = sys.argv

    infiles = [f for f in os.listdir(indir) if os.path.isfile(os.path.join(indir, f))]

    for infile in infiles:
        outfile = re.sub(r'abc', r'year' , infile)
        os.rename(os.path.join(indir, infile), os.path.join(indir, outfile))

这是我的解决方案，它在每个步骤中都写有注释，以便即使是新手也可以理解和使用，修改和自定义：

＃通过更改代码中的一行，我认为该行将起作用，或者可能不改变任何行将起作用

import glob2
import os


def rename(f_path, new_name):
    filelist = glob2.glob(f_path + "*.ma")
    count = 0
    for file in filelist:
        print("File Count : ", count)
        filename = os.path.split(file)
        print(filename)
        new_filename = f_path + new_name + str(count + 1) + ".ma"
        os.rename(f_path+filename[1], new_filename)
        print(new_filename)
        count = count + 1

通过传递两个参数f_path作为您的路径，并传递您想要提供给文件的new_name来调用该函数。

Answer 5

这允许使用创建date_time重命名文件。

import os, datetime, time

folder = r"*:\***\***\TEST"

for file in os.listdir(folder):
    date = os.path.getmtime(os.path.join(folder, file))
    new_filename = datetime.datetime.fromtimestamp(date).strftime("%Y%m%d_%H%M%S.%f")[:-4]
    os.rename(os.path.join(folder, file), os.path.join(folder, new_filename + ".pdf"))
    print("Renamed " + file + " to " + new_filename)
    time.sleep(0.1)

Answer 6

import os
import glob

path = 'C:\\Users\\yannk\\Desktop\\HI'
file_num = 0
for filename in glob.glob(os.path.join(path, '*.jpg')):
    os.rename(filename, path + '\\' + str(file_num) + '.jpg')
    file_num += 1

这是将文件夹中的所有文件重命名为它们在文件夹中位置的缩进，您应该可以将此代码抓起来并用于您的目的。这是给在Windows上的人使用的，因此os.cwd或os.getcwd无法正常工作

Answer 7

检查是否存在具有 new_name 的文件。如果不存在文件，则继续重命名文件。

for file in files:
    parts = file.split('_') # Existing file name
    new_name = 'year_{}'.format(parts[1]) #New file to be written
    if not os.path.exists(new_name):
        os.rename(file, new_name)

在Python中重命名多个文件
