Question

Write a Python program to read lines of text from a file. For each word (i.e, a group of characters separated by one or more whitespace characters), keep track of how many times that word appears in the file. In the end, print out the top twenty counts and the corresponding words for each count. Print each value and the corresponding words, in alphabetical order, on one line. Print this in reverse sorted order by word count.

You can assume that there is no punctuation and that all of the words are lower case.

Hard-code the name of the input file as input.asc.

Answer 1

#input.asc

write a python program to read lines of text from a file
for each word a group of characters separated by one or more whitespace characters keep track of how many times that word appears in the file
in the end print out the top twenty counts and the corresponding words for each count
print each value and the corresponding words, in alphabetical order on one line
print this in reverse sorted order by word count

#source.py

f=open("input.asc","r")
temp=[]
for line in f.readlines():
   sublist=line.split(" ")
   sublist[len(sublist)-1]=sublist[len(sublist)-1].replace("\n","")
   temp.append(sublist)
list=[]
for i in range(len(temp)):
   for j in range(len(temp[i])):
       list.append(temp[i][j])
sub_unique=set(list)
data=[]
for i in sub_unique:
   a=list.count(i)
   data.append([i,a])
print(data) #cout the data
value=sorted(data,key = lambda i: i[1],reverse=True)
for i in range(20):
   print(value[i]) #top 20 values based on count
print(sorted(data)) #alphabetical order
tempc=sorted(data)
print("\n")
for i in range(len(tempc)):
   tempc[i][0],tempc[i][1]=tempc[i][1],tempc[i][0]
print(tempc)
  
  
#output:
