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.

The program counts the number of times a certain alphabet occurs in a particular sentence or word supplied by user. The program is written in python 3 thus :

user_input = input('Enter phrase : ')

#prompts user for input

char_to_count = user_input[0]

#subset the letter to count as it is the first of the input string

word = user_input[1:]

#subset the word

num_counts = word.count(char_to_count)

#count the number of times the alphabet occurs using the count function

if char_to_count in word :

#check if the character to count occurs in the word

print(num_counts)

#display the number of times in occurs

else :

print(0)

#ifit doesn't occur print 0
