计算列表中的出现次数

Question

I am loading numbers from a text file into a list, and in that regard, everything works fine! But now I need to know how many times each number occured in the list. Below is my whole program that I have pieced together by searching this site.

row = []  
textfile = open('take5_3.txt', 'r')
yourResult = [line.split('-') for line in textfile]
row.append(yourResult)    
print (yourResult)    

Any time I put some sort of line that is suppose to count my result, I get one because it is only counting the list and not the items within the list.

Answer 1

As Joran has commentted, your question is really not clear. I will try to fill in the blank here.

textfile = open('take5_3.txt', 'r')
yourResult = [line.split('-') for line in textfile.readlines()] # use readline to read from the file
# You probably need to flatten the content in yourResult.
# Assume now yourResult is something like this ['a', 'a', 'bdbd', 'bbc', 'bbc']
# you can use Counter to do the counting
from collections import Counter
print Counter(yourResult)

And here is the output

Counter({'a': 2, 'bbc': 2, 'bdbd': 1})

You'll need to make a dictionary with the number as the key and the count of the number as the value. just keep incrementing the value as you go along.
