Answer»

phonebook=dict( )

n=input(” Enter total number of friends to create a telephone book”)

i=l

while i<=n:

a=raw_input(“enter name”)

b=raw_input(“enter phone number”)

phonebook[a]=b

i=i+l

name=raw_input(“enter friend’s name to search for”)

f=0

l=phonebook.keys( )

for i in l:

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

print “Phone number= “,phonebook[i]

f=l

if (f==0):

print “Given name not exist”
