Python 递归重命名文件扩展名
我很难创建一个python脚本来重命名文件夹中的文件扩展名,并在子目录中继续这样做。这是我迄今为止的剧本;它只能重命名顶级目录中的文件:Python 递归重命名文件扩展名,python,Python,我很难创建一个python脚本来重命名文件夹中的文件扩展名,并在子目录中继续这样做。这是我迄今为止的剧本;它只能重命名顶级目录中的文件: #!/usr/bin/python # Usage: python rename_file_extensions.py import os import sys for filename in os.listdir ("C:\\Users\\username\\Desktop\\test\\"): # parse through file list in
#!/usr/bin/python
# Usage: python rename_file_extensions.py
import os
import sys
for filename in os.listdir ("C:\\Users\\username\\Desktop\\test\\"): # parse through file list in the folder "test"
if filename.find(".jpg") > 0: # if an .jpg is found
newfilename = filename.replace(".jpg","jpeg") # convert .jpg to jpeg
os.rename(filename, newfilename) # rename the file
您可以按如下方式处理目录:
import os
def process_directory(root):
for item in os.listdir(root):
if os.path.isdir(item):
print("is directory", item)
process_directory(item)
else:
print(item)
#Do stuff
process_directory(os.getcwd())
for subdir, dirs, files in os.walk(root):
for f in files:
if f.find('.jpg') > 0:
#The rest of your stuff
尽管如此,这并不是真的必要。只需使用os.walk
,它将遍历所有顶级目录和其他目录/文件如下操作:
import os
def process_directory(root):
for item in os.listdir(root):
if os.path.isdir(item):
print("is directory", item)
process_directory(item)
else:
print(item)
#Do stuff
process_directory(os.getcwd())
for subdir, dirs, files in os.walk(root):
for f in files:
if f.find('.jpg') > 0:
#The rest of your stuff
这正是你想要的
import os
import sys
directory = os.path.dirname(os.path.realpath(sys.argv[0])) #get the directory of your script
for subdir, dirs, files in os.walk(directory):
for filename in files:
if filename.find('.jpg') > 0:
subdirectoryPath = os.path.relpath(subdir, directory) #get the path to your subdirectory
filePath = os.path.join(subdirectoryPath, filename) #get the path to your file
newFilePath = filePath.replace(".jpg",".jpeg") #create the new name
os.rename(filePath, newFilePath) #rename your file
我用文件路径修改了Jaron的答案,重命名文件的完整示例我稍微修改了Hector Rodriguez Jr.的答案,因为它将替换路径中出现的任何
“.jpg”
,例如/path/to/my.jpg.files/001.jpg
将变成/path/to/my.jpg.files/001.jpeg>,这不是你想要的,对吧
虽然在文件夹名称中使用点通常不是一个好主意,但它也可能发生
import os
import sys
directory = os.path.dirname(os.path.realpath(sys.argv[0])) # directory of your script
for subdir, dirs, files in os.walk(directory):
for filename in files:
if filename.find('.jpg') > 0:
newFilename = filename.replace(".jpg", ".jpeg") # replace only in filename
subdirectoryPath = os.path.relpath(subdir, directory) # path to subdirectory
filePath = os.path.join(subdirectoryPath, filename) # path to file
newFilePath = os.path.join(subdirectoryPath, newFilename) # new path
os.rename(filePath, newFilePath) # rename
这可能是重复的正是我要找的!将它放在目录的根目录中并运行它。它将为根目录和子目录中的所有内容更改相应的扩展名!令人惊叹的!os.getcwd()可以替换os.path.dirname(os.path.realpath(sys.argv[0]))
