Python输出帮助，使频率列表从另一个文件中读取

Question

So I know how to extract the words I need from the file, but what I don't quite understand is how to integrate a loop counting the frequency of my extracted words. Here's what I have:

myfile = open('sample.pos')
file = open('sample.sorted', 'w')
line = myfile.readline()
list =[]

while line:
     line = myfile.readline()
     line.strip()
     if len(line) > 1:
         list.append(line)
list.sort()

x=0
while x < len(list):

     ll=list[x].split()
     file.write(ll[1] + '\n')
     x = x +1

myfile.close()
file.close()

I wanted to take my first list and using a loop count my word frequencies using something like this.

list = []  
list2 = []    

for word in list:
     if word in list2:
         list2.index(word)[1] += 1
else:
    list2.append([word,0])

I'm just incredibly stuck in how to integrate this with the file.write and my current code. The end result is to have each word listed on a separate line with its frequency. What I get currently is just a list.

myfile = open('sample.pos')
file = open('sample.sorted', 'w')
list =[]

for line in myfile:
  line.strip()
  if len(line) > 1:
    list.append(line)

list2 = []    

for word in list:
  if word in [x for x in list2[0]]:
     list2.index(word)[1] += 1
else:
  list2.append([word,0])

but using dict would probably be better

wordCount = {}
for word in list:
  if word in wordCount.keys():
    wordCount[word] += 1
  else:
    wordcount[word] = 0

then you can access any word's count by wordCount[word]
