我给包含许多行像下面......许多随机信息的Python：通过
Spiaks餐厅的文本文件列表遍历| 42.74 | -73.70 | 2阿奇博尔德ST +华特甫，NY 12189 | http://www.yelp.com/biz/spiaks-restaurant-watervliet|Italian|4|5|4|3|3|4|4
例如，Spiaks餐厅是在位置0，42.74是在位置1，-73.70处于位置2 ....意大利处于位置5 ... 4 | 5 | 4 | 3 | 3 | 4 | 4是另一列表...所以基本上列表内的列表，以及数字4是在6位，5在7位..等
我必须询问用户，并且用户应该回复：
What type of restaurant would you like => Italian
What is the minimum rating => 3.6
结果应该是：
Name: Spiaks Restaurant; Rating 3.86
Name: Lo Portos; Rating 4.00
Name: Verdiles Restaurant; Rating 4.00
Found 3 restaurants.
这里是我的代码：
rest_type = raw_input("What type of restaurant would you like => ")
min_rate = float(raw_input("What is the minimum rating => "))
def parse_line(text_file):
count = 0.0
a_strip = text_file.strip('\n')
b_split = a_strip.split('|')
for i in range(6, len(b_split)):
b_split[i] = int(b_split[i]) # Takes the current indices in the list and converts it to integers
count += b_split[i] # Add up all of the integers values to get the total ratings
avg_rate = count/len(b_split[6:len(b_split)]) # Takes the total ratings & divides it by the length
#The above basically calculates the average of the numbers like 4|5|4|3|3|4|4
if (rest_type == b_split[5] and avg_rate >= min_rate):
print b_split[0], avg_rate
与结果的问题..我得到：
None
我知道这是一个很长很长的问题，但如果有人能给我一些见解，我将不胜感激！
