Python里面for循环readlines单输出

Question

我有以下脚本正确识别ASCII和非ASCII行，但我想每个文件，而不是每行的报告。由于我在循环内部有print，并且我有很多文件，所以输出得太多了。 如何修改此代码以获得每个文件的单个输出？它应该告诉我文件中是否有非ASCII文本。

import os 

for file in os.listdir('.'): 
    if file.endswith('.txt'): 

     with open(file) as f: 
      content = f.readlines() 

      for entry in content: 
       try: 
        entry.encode('ascii') 
       except UnicodeEncodeError: 
        print("it was not a ascii-encoded unicode string") 
        print(file) 
       else: 
        print("It may have been an ascii-encoded unicode string") 
        print(file)

举例来说，如果你想显示是否有文件中的任何非ASCII字符串，你保持一个标志，告诉你，你是否已经找到了一个坏线。但是，您需要等到文件结束才能报告。

import os 

for file in os.listdir('.'): 
    if file.endswith('.txt'): 

     with open(file) as f: 
      content = f.readlines() 
      good_file = True 

      for entry in content: 
       try: 
        entry.encode('ascii') 
       except UnicodeEncodeError: 
        good_file = False 

     if good_file: 
      print("It may have been an ASCII-encoded unicode string") 
     else: 
      print("it was not an ASCII-encoded unicode string") 

     print(file)
