Trouble displaying items from lists

[Liquid_Ocelot]

It looks as if names is a list.
try print(names) to see.
if so, you can find the index of the one you want by using index

idx = nicknames.index('nick')
del nicknames[idx]

not tested, but should be OK

Yeah names is part of a list that has been put into a dictionary (thanks to your previous post xD)

So I have written

def deletecontact():
            delname = input('Who would you like to delete (Enter nickname):')
            for nick in nicknames:
                if delname in nicknames:
                    reply = input("Delete Contact? "+str(Names)+"? [y/[n]] ")
                    if delname not in nicknames:
                        print ("This Contact Does Not Exist!!\n----------------------\n")
                if reply=='y':
                        idx = nicknames.index(delname)
                        del nicknames[idx]
                        print('Contact has been DELETED')
            menu()

That seems to have done it using the index method :)

Now I just need to print a message to tell the user that there are no contacts listed if they go to show contacts and nothing is in the list because if I do that now I get this error 

    print ("--------------------" + "\n" + str(nicknames[i]) + "\n" + str(Names[i]) + "\n"  +  str(Numbers[i]) + "\n"  +  str(address[i]) + "\n" + "--------------------")

IndexError: list index out of range

Not too sure but I may have figured it out and I really do apologize if I butcher this explanation

So I can save contacts just fine and print them that is cool but when I go to delete a contact (by searching its nickname) then again call the function to show the list of contacts it throws up the

IndexError: list index out of range

To explain this here is the input and output:

import sys
Numbers=[]
Names=[]
nicknames=[]
address=[]
from collections import defaultdict

x = [Numbers, Names, nicknames, address]
len_dict = defaultdict(list)
for word in x:
   len_dict[len(word)].append(word)
len_dict

def addcontact():
       print ("-------------")
       print ("Adding a Contact\n-------------")
       name = input("Enter first and last name :")
       Names.append(name)
       nickname = input("Enter the nickname")
       nicknames.append(nickname)
       number = input("Enter number :")
       Numbers.append(number)
       Addres = input("Enter the address")
       address.append(Addres)
       print("***Contact added successfully***")
       menu()

def searchcontact():
       print ("\nSearch Contact by Nickname\n--------------------")
       nick = input("Please enter the nicnkname")
       for nick in nicknames:
               if nick in nicknames:
                   print ("The Contacts are listed Below")
                   print ("-----------------------------")
                   index = nicknames.index(nick)
                   print ("\n", nicknames[index])
                   print ("\n",Names[index])
                   print ("\n",address[index])
                   print ("\n", Numbers[index])
       if nick not in nicknames:
               print ("\nThis Contact Does Not Exist!!\n----------------------\n")
       menu()

def showcontact():
       for i in range(len(Names)):
           print ("--------------------" + "\n" + str(nicknames[i]) + "\n" + str(Names[i]) + "\n"  +  str(Numbers[i]) + "\n"  +  str(address[i]) + "\n" + "--------------------")
       menu()

def deletecontact():
           delname = input('Who would you like to delete (Enter nickname):')
           for nick in nicknames:
               if delname in nicknames:
                   reply = input("Delete Contact? "+str(Names)+"? [y/[n]] ")
                   if delname not in nicknames:
                       print ("This Contact Does Not Exist!!\n----------------------\n")
               if reply=='y':
                       idx = nicknames.index(delname)
                       del nicknames[idx]
                       print('Contact has been DELETED')
           menu()

def quit():
       print("Exiting....")
       sys.exit


def menu():
       print ("---------------------------------------")
       print  ("***Welcome to the Python address book***\n"+
               "\n----------------------------------------"+
               "\n| 1 | Add Contact"+
              "\n| 2 | To search for the contact by nickname\n| 3 | To list all contacts in the address book\n| 4 | Delete Contact\n| 5 | Quit"+"\n"
               "----------------------------------------\n")
menu()

while True:
       selection = input("Please Select :")
       if selection =='1': addcontact()
       elif selection =='2': searchcontact()
       elif selection =='3': showcontact()
       elif selection == '4': deletecontact()
       elif selection == '5': quit()
       else:
           print ("Unknown Command")
           menu()
selection = input("Please Select:")

And then the output:
