[英]Recursively rename file extensions
我在創建一個 python 腳本時遇到了困難,該腳本將重命名文件夾中的文件擴展名並繼續在子目錄中這樣做。 這是我迄今為止的腳本; 它只能重命名頂級目錄中的文件:
#!/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 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
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
我用文件路徑和重命名文件的完整示例修改了 Jaron 的答案
我稍微修改了 Hector Rodriguez Jr. 的答案,因為它會替換路徑中出現的任何".jpg"
,例如/path/to/my.jpg.files/001.jpg
會變成/path/to/my.jpeg.files/001.jpeg
,這不是你想要的,對吧?
盡管使用點"."
通常不是一個好主意"."
在文件夾名稱中,它可能發生...
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
您可以像這樣處理目錄:
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())
雖然,這並不是真正必要的。 只需使用os.walk
將遍歷所有頂級和進一步的目錄/文件
這樣做:
for subdir, dirs, files in os.walk(root):
for f in files:
if f.find('.jpg') > 0:
#The rest of your stuff
那應該完全符合您的要求。
