Working code, but it needs one more function(def) to display the menu as mention in the directions and it gives an error that needs to be fixed.
def func1(m):
name=input("Enter a name:")
if name in m:
print("Name: ",name)
print("Email: ",m[name])
else:
print("The specified name was not found")
def func2(m):
name=input("Enter name: ")
email=input("Enter email address: ")
if name in m:
print("That name already exists")
else:
m[name]=email
print("Name and address have been added")
return m
def func3(m):
name=input("Enter name: ")
email=input("Enter the new address: ")
if name in m:
m[name]=email
print("Information updated")
return m
def func4(m):
name=input("Enter name: ")
if name in m:
del m[name]
print("Information deleted")
return m
else:
print("The specified name was not found")
menu={}
flag=True
while(flag):
print("Menu")
print("----------------------------------------")
print("1. Look up an email address")
print("2. Add a new name and email address")
print("3. Change an existing email address")
print("4. Delete a name and email address")
print("5. Quit the program")
print()
n=int(input("Enter your choice: "))
if(n==1):
func1(menu)
elif(n==2):
menu=func2(menu)
elif(n==3):
menu=func3(menu)
elif(n==4):
menu=func4(menu)
elif(n==5):
print("Information saved")
flag=False
Upvote for adding one more function ''def'' and fixing the error from the already existing code.
