9.18 LAB: Count characters Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase. Ex: If the input is: n Monday the output is: 1 Ex: If the input is: z Today is Monday the output is: 0 Ex: If the input is: n It's a sunny day the output is: 2 Case matters. Ex: If the input is: n Nobody the output is: 0 n is different than N.

i = 0

word = input ('Enter character and phrase: '). lower (). split ()

phrase = ' '. join (word[1:])

a = word[0]

for char in phrase:

if char = = a:

i + = 1

print (i)

Explanation:

The programming language used is python.

we initialize the counter 'i' that will be used to count how many times a letter occurs.

The program then prompts the user for an input, converts it to lowercase and also, converts it to a list.

The phrase is extracted using a list slice and converted back to a string using the join function, the the character that is to be scanned for is assigned to a variable.

Using a FOR loop and an IF statement we check for every character in the phrase and increase the count by one for each time a character appears.

Finally, the result is printed to the screen.
