I have been working on this small project in order to fetch top-notch images from Reddit. Overall I am pretty confident about the code below but I am not entirely sure about whether my error handling conforms to best practices or not. (Obviously account-related data has been 'censored'.) Thoughts?

#!/usr/bin/env python3

import os
import praw # reddit API Wrapper
from urllib.error import URLError, HTTPError
import urllib.request as web
import shutil # shell utilities
import colorama
from colorama import Fore, Style

def main(subreddit_name = 'all', current_dir = os.getcwd()):
 reddit = praw.Reddit(
 client_id = 'censored', 
 client_secret = 'censored', 
 username = 'censored', 
 password = 'censored', 
 user_agent = 'subreddit crawler')

 dir_path = os.path.join(current_dir,subreddit_name)
 if not os.path.exists(dir_path):
 os.mkdir(dir_path)

 colorama.init(autoreset = True)
 subreddit = reddit.subreddit(subreddit_name).top(limit=1000)

 print("Download files...")

 for submissions in subreddit:
 if not submissions.stickied and submissions.score > 50:
 fullfilename = os.path.join(dir_path, ".jpg".format(submissions))
 request = web.Request(submissions.url, headers = 'User-Agent':'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0')
 with web.urlopen(request) as response, open(fullfilename, 'wb') as out_file: 
 try:
 shutil.copyfileobj(response, out_file)
 except HTTPError as e:
 print("".format(Fore.RED, e.code, Style.RESET_ALL))
 except URLError as e:
 print("".format(Fore.RED, e.reason, Style.RESET_ALL)) 

 # delete corrupted files smaller than 55 KB
 filesize = os.path.getsize(fullfilename)
 if filesize < 55000:
 os.remove(fullfilename)
 else:
 # this is for debugging purposes only
 temp = "[:07dKB]".format(Fore.GREEN, filesize, Style.RESET_ALL)
 print(" ID: URL: ".format(temp, submissions, submissions.url))

 dir_count = len(os.listdir(dir_path))
 print("Download succeeded. files saved in ''.".format(dir_count, dir_path))
