下面是一个完整的示例,包含了检查文件夹是否存在和创建文件夹两个步骤: importosdeffolder_exists(folder_path):returnos.path.exists(folder_path)defcreate_folder(folder_path):os.makedirs(folder_path)folder_path="my_folder"ifnotfolder_exists(folder_path):create_folder(folder_path)print(f"文件夹{folder...
create_floder.py importos folder_max=10foriinrange(0,folder_max):# 创建folder_max个文件夹folder_name="%02d"%(i)ifnotos.path.exists(folder_name):os.mkdir(folder_name) 实验结果:
import os ls = os.linesep #为os.linesep取了一个别名 当前平台的换行符 while True:fname = raw_input('input a file name to save filenames:%s' % ls)if os.path.exists(fname):#os.path.exists（path）判断path是否存在 print ('error: %s already exsit', fname)else:print 'save...
