temp=100
n=input("Enter the number of contacts : ")
for i in range(0,n):
    name1=raw_input("Enter your name: ")
    num=input("Enter your phone number: ")
    list1.extend([name1])
    list2.extend([num])
    dict1=dict(zip(list1,list2))#to convert two list into dictionary
print dict1

print """

         3:Delete a contact

You search a dictionary in this way, and note that names would be case sensitive:

def search(dict1):
    name2=raw_input("Enter the name whose number is to be found: ")
    if name2 in dict1:
        print name2, dict1[name]
