Question

A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes in word pairs that consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name.
Ex: If the input is:
Joe 123-5432 Linda 983-4123 Frank 867-5309
Frank
the output is:
867-5309
Python 3 please.

Answer 1

Answer:

# The user in prompted for input and stored in userInput

userInput = str(input("Enter the contact: "))

# The user input is splitted and stored in splitUserInput

# splitUserInput is a list because split returns a list

splitUserInput = userInput.split(" ")

# The user is prompt to enter the search contact

# The search contact will have the first letter capitalize

# should it be entered in lower case all through

searchContact = str(input("Enter the search contact: "))

# loop through the list

for i in range(len(splitUserInput)):

   # compare if the string at any value of i

   # is the same as the searchContact

   # we display the string ahead of it

   # by adding 1 to the index

   if(splitUserInput[i] == searchContact):

       print(splitUserInput[i + 1])

Explanation:

A sample screenshot is attached. The code is written in Python 3 and well commented.

The program prompt the user for input then split the input into a list. It then asked for a contact to search for. It begins looping through the list, if the search contact is found at any index, then it prints what is in front of the index.
