在我的python代码中是否有可能实现紧凑的IF语句？

目前我有3条If语句是这样做的：

if filetype not in filetypes:
     print(f'  SKIPPED - WRONG FILETYPE: {filetype}')
     continue
elif 'comments' in meme_url or 'gallery' in meme_url:
     print('  SKIPPED - NOT A MEME')
     continue
elif meme_id in memes or meme_id in used_memes:
     print('  SKIPPED - USED')
     continue
            

def filter_by_name(filename, meme_url, used_memes):
    '''
    Returns True if filtered IN for more processing. False, if filtered out.
    '''

filters = [filter_by_name, filter_by_comment, filter_by_id]

filtered_out = False
for filter_function in filters:
    if not filter_function(filename, meme_url, used_memes):
        print(f'Not selected because did not pass through {filter_function}')
        filtered_out = True
        break
  
if filtered_out:
    continue
# Passed though all filters so process more

这些是对无效图像的排序，我希望能够追溯哪个“过滤器”起作用（目前是通过打印（“问题”）完成的）

尽管如此，这段代码“闻起来”很糟糕，所以我对更智能的解决方案感兴趣，如果有的话。提前感谢。

您可以这样做：

if filetype not in filetypes:
     print(f'  SKIPPED - WRONG FILETYPE: {filetype}')
     continue
elif 'comments' in meme_url or 'gallery' in meme_url:
     print('  SKIPPED - NOT A MEME')
     continue
elif meme_id in memes or meme_id in used_memes:
     print('  SKIPPED - USED')
     continue
            

def filter_by_name(filename, meme_url, used_memes):
    '''
    Returns True if filtered IN for more processing. False, if filtered out.
    '''

filters = [filter_by_name, filter_by_comment, filter_by_id]

filtered_out = False
for filter_function in filters:
    if not filter_function(filename, meme_url, used_memes):
        print(f'Not selected because did not pass through {filter_function}')
        filtered_out = True
        break
  
if filtered_out:
    continue
# Passed though all filters so process more

但正如在评论中提到的，您将拥有一个函数，其中包含一些他们甚至不使用的参数。

它们都使用（基于）不同的标准进行过滤。即使将它们放在单独的函数中，也会有一些函数带有无关的参数？你有3个独立的条件，所以你有3个检查。
