重命名文件夾下的所有文件
import os
def rename_file():
# get files' names from a diretory
file_list = os.listdir(r"C:\Users\Administrator\Desktop\prank")
save_path = os.getcwd() # Return a string representing the current working directory
# print("Current Working Directory is "+save_path)
# Change the current working directory to path
os.chdir(r"C:\Users\Administrator\Desktop\prank")
# rename each file
for file_name in file_list:
map = file_name.maketrans('a','a','0123456789')
os.rename(file_name, file_name.translate(map))
rename_file()
或者可以使用re.sub來(lái)替換学搜，本例中替換數(shù)字可以為：re.sub(r'[0-9]+', '', file_name)
注：當(dāng)文件已存在時(shí)，無(wú)法創(chuàng)建該文件
