Question

Write a Python program to input ‘n’names and phone numbers to store it in a dictionary and to search and print the phone number of that particular name.

Answer 1

Answer:

Explanation:

phonebook = dict( )  

n = input (“Enter total number of friends”)

i = 1  while i<=n :  a = raw_input (“Enter name”)  b = raw_input (“Enter phone number”)

phonebook [a] = b i = i + 1  name = raw_input (“Enter name”)  f = 0  l = phonebook.keys( )  for i in l :  if (comp (i, name) = = 0) :  print “Phone number =”, phonebook[i]  f = 1  if (f = = 0):  print “Given name not exist”

Answer 2

The program is given below:

phonebook_directory = dict( )

n = input (” Enter number of friends you want to add with their phone numbers”)          // enter the name

A = x

while A < = n :   // while loop

y = raw_input (“enter name”)    // name is given as input

z = raw_input (“enter phone number”)   // phone number is given as input

phonebook_directory [y] = z

A = A + x

name = raw_input (“enter the name to be searched ”)   // searching of name

g = 0

K= phonebook_directory . keys( )   // keys are checked

for A in x :

if (cmp(A,name) == 0):

print ( “Phone number= “ , phonebook_directory[A] )     // output is printed

g = x

if (g==0):

print ( “Unknown name” )    //when name does not match with the stored names
