Question

write a python program to Count the number of times a character appears in

a given string using a dictionary​

Answer 1

Given a string, the task is to count the frequency of a single character in that string. This particular operation on string is quite useful in many applications such as removing duplicates or detecting unwanted characters.

Method #1 : Naive method

Iterate the entire string for that particular character and then increase the counter when we encounter the particular character.

# Python3 code to demonstrate
# occurrence frequency using
# naive method


# initializing string

test_str = "GeeksforGeeks"


# using naive method to get count
# counting e

count = 0



for i in test_str:

if i == 'e':

count = count + 1


# printing result

print ("Count of e in GeeksforGeeks is : "

+ str(coun

Answer 2

Answer:

str = input("Enter the string: ")

ch = input("Enter the character to count: ");

c = str.count(ch)

print(ch, "occurs", c, "times")

OUTPUT

Enter the string: KnowledgeBoat

Enter the character to count: e

e occurs 2 times
