Question

Python:

Write a program that lets the user enter a string and displays the letter that appears most frequently in the string, ignore spaces, punctuation, and Upper vs Lower case.

Create a list to hold letters based on the length of the user input

Convert all letters to the same case

Use a loop to check for each letter in the alphabet

Have a variable to hold the largest number of times a letter appears, and replace the value when a higher number is found

Answer 1

Here is code:

#initially added 26 letter array

count = [0] * 26

#read input

str = input("Enter a string : ")

#loop the string

for i, c in enumerate(str):

if(c.isalpha()):

#find index of character find the index a = 0 , b= 1,c = 2 ..... z = 26

index = ord(c.lower()) - 97

# increment the value of index

count[index] = count[index] + 1

max = 0

#find max index value

for i in range(26):

if(count[max] < count[i]):

max = i

print("The max time character occurred is : ",chr(max + 97))

#initially added 26 letter array count [0] * 26 #read input str-input ("Enter a string) #loop the string for i, c in enumerate(str): if(c.isalpha()) #find index of character find the index a index ord(c.lower()) - 97 # increment the value of index count [index] -count[index] 1 b- 1,c 2 z26 , #find max index value for i in range(26): if(count[max] count[i]): max i print("The max time character occurred is,chr(max 97))

Output:

Enter a string sample@ string The max time character occurred iss
