這是一個讀寫檔案和合並檔案的範例

讀入了基礎詞庫的路徑based_file_path和新增詞庫的路徑added_file_path，將詞庫合併去重後寫入merge_file_path路徑下的檔案

def merge_dict_func(based_file_path, added_file_path, merge_file_path):
    based_file_object = open(based_file_path, 'r')
    added_file_object = open(added_file_path, 'r')
    merge_file_object = open(merge_file_path, 'w')

    based_set = []
    added_set = []
    merge_set = []

    for line in based_file_object:
        based_set.append(line)
    for line in added_file_object:
        added_set.append(line)
    for added_x in added_set:
        if added_x not in based_set:
            merge_set.append(added_x)
    for based_x in based_set:
        merge_set.append(based_x)
    for merge_x in merge_set:
        if merge_x != None:
            merge_file_object.write(merge_x)

    merge_file_object.close()
    based_file_object.close()
    added_file_object.close()

if __name__ == '__main__':
    if based_file_path != None and added_file_path != None and merge_file_path != None:
        merge_dict_func(based_file_path, added_file_path, merge_file_path)
    print 'merge_dict_util process finished.'</span>
