Question

Write a program that prompts the user to enter a file name and displays the occurrences of each letter in the file. Letters are case-insensitive. Here is a sample run:

Enter a filename: Lincoln.txt

Number of A’s: 23

Number of B’s: 0

Number of C’s: 12

……

Number of Y’s: 5

Number of Z’s: 7

Answer 1

x=input("Enter File Name:") #TO take input file name from the user
file=open(x,'r') #opening the requested file with read access
x=file.read() #reading the content of the file
for i in range(ord('A'),ord('Z')+1): #ord reveal the ASCII values of the chahracter
print("NUMBER of "+chr(i)+"'s: ",x.count(chr(i))+x.count(chr(i+32))) #chr() used to convert ASCII to characters

#We counted considering string as case insensitive
