Question

Write a program that counts the frequency of each letter of the alphabet as they occur in a text contained in a text file.

The program should read all the characters from a file and tally the frequency for each letter of the alphabet (case-insensitive), along with white space and total character count.

Your program's data structure will eventually contain the 26 numbers that will represent the frequencies of occurrence of all 26 letters of the alphabet in that file.

You should take advantage of how letters are encoded in the ASCII table and that you can perform arithmetic with char's.

Answer 1

Here is the answer..

CODE:

keys = [chr(i) for i in range(65,ord('Z')+1)]
values = [0 for i in range(1,27)]
d = {k:v for k,v in zip(keys,values)}
file = open('words.txt','r')
s = file.read()
s=s.upper()
#print(len(s))
space_count=0
total_count=0
for i in s:
if(i==" "):
space_count+=1
elif(i>='A' and i<='Z'):
d[i]=d.get(i,0)+1
total_count+=1
print("space count : ",space_count)
print("Total count : ",total_count)
print("alphabets : ",d)
