Python [Errno 17] File exists Issue -

in python, when folder created first time, directory created , files created in folder path. when again new file needs created in same location, i'm getting error:

[errno 17] file exists: '/home/test/files/tweets/'. 

any suggestions please?

if len(downloadedfile) > 0:     #insert_time=time.strftime('%y_%-m_%-d')     #download_path='/home/test/files/tweets/'     #file_path= download_path+insert_time+"/"+hashes     #print(file_path)     = datetime.now     new_folder = '/home/test/files/tweets/{}'.format(now().strftime('%y_%-m_%-d'))     os.mkdir(new_folder, 0755 );     folder_path = new_folder+"/"+hashes     fo = open(folder_path,"wb")     fo.write(downloadedfile)     fo.close()     print("file downloaded") else:    print("file not downloaded") 

catch oserror try:except::

try:     os.mkdir(new_folder, 0755) except oserror:     pass 

this bit unsatisfactory, there other errors might ignore.
