Question

我有一个脚本，用于从最大模糊比率中找到最佳文件。所选文件将进一步使用。但是我得到了这个错误：

    with open(best_fuzzy_file,'r') as file:
NameError: name 'best_fuzzy_file' is not defined
>>>

请帮我修改我的代码！我的代码：

for j in cursor.fetchall():
    s1=j[0]

    def good_ratio(a):
        return fuzz.token_set_ratio(a, s1) 
    for dir_entry in os.listdir(path):
        dir_entry_path = os.path.join(path, dir_entry)
        if os.path.isfile(dir_entry_path):

            condition_matched_in_file = False
            with open(dir_entry_path, 'r') as my_file:
               try:
                   my_sum, my_len = reduce(lambda a, b: (a[0]+b[0], a[1]+b[1]), ((good_ratio(i), 1) for i in my_file))
               except TypeError:
                   # file empty, move to next file
                   continue
               fuzzinessav=(my_sum/my_len)
               filenames2fuzz[dir_entry_path].append(fuzzinessav)
            best_fuzziness_ratio = 0  
            for k, v in filenames2fuzz.items():                       
                    if max(v) > best_fuzziness_ratio:
                        best_fuzzy_file = k                        
                        best_fuzziness_ratio = max(v)
    with open(best_fuzzy_file) as f:   #<-Gets me an error
                print best_fuzzy_file

import os
for j in cursor.fetchall():
    best_fuzzy_file = ''
    s1=j[0]

    def good_ratio(a):
        return fuzz.token_set_ratio(a, s1) 
    for dir_entry in os.listdir(path):
        dir_entry_path = os.path.join(path, dir_entry)
        if os.path.isfile(dir_entry_path):

            condition_matched_in_file = False
            with open(dir_entry_path, 'r') as my_file:
               try:
                   my_sum, my_len = reduce(lambda a, b: (a[0]+b[0], a[1]+b[1]), ((good_ratio(i), 1) for i in my_file))
               except TypeError:
                   # file empty, move to next file
                   continue
               fuzzinessav=(my_sum/my_len)
               filenames2fuzz[dir_entry_path].append(fuzzinessav)
            best_fuzziness_ratio = 0  
            for k, v in filenames2fuzz.items():                       
                    if max(v) > best_fuzziness_ratio:
                        best_fuzzy_file = k                        
                        best_fuzziness_ratio = max(v)
    if os.path.exists(file_location+'/'+best_fuzzy_file): # can be checked using other modules
         with open(best_fuzzy_file) as f:
             print best_fuzzy_file

我已经定义了＆＃39; best_fuzzy_file n＃39;在for循环的开头，使用os模块预先检查文件..
