我得到一个文本文件,其中包含许多行,如下所示...许多随机信息
Spiaks 餐厅|42.74|-73.70|2 Archibald St+Watervliet, NY 12189| http://www.yelp.com/biz/spiaks-restaurant-watervliet|意大利语|4|5|4|3|3|4|4
例如,Spiaks Restaurant 位于位置 0,42.74 位于位置 1,-73.70 位于位置 2.... Italian 位于位置 5... 4|5|4|3|3|4|4 是另一个列表...所以基本上是一个列表中的一个列表,数字 4 将位于第 6 位,5 位于第 7 位 .. 等等
我必须问用户,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
结果的问题是..我得到:
None
我知道这是一个非常非常长的问题,但如果有人能给我一些见解,我将不胜感激!
