修正和評論，它們主要是語法錯誤。menulist= '''1. Print the list,

2. Add a name to the list,

3. Remove a name from the list,

4. Change an item in the list,

9. Quit''' #assuming you want to display menulist, having it as a tuple is useless

lst=("johny","tom","kim","tim","jim") #don't use reserved names for variables, may mess up things

target=raw_input("Pick an item from the menu:")

if target=="1": #this is an equality operator, whereas = is used to assign a variable (This checks the equality basically)

print lst

elif target=="2":

Addname=raw_input("Type in a name to add:")

list=list.append(Addname) #use append instead of insert, insert is for a specific position in list

print menulist #no parentheses, menulist is not a function; also this doesn't have to be indented

elif target=="3":

Removename=raw_input("What name would you like to remove:")

list=list.remove(Removename)

print menulist #again, I took the parentheses away

elif target=="4":

Changename=raw_input("What name would you like to change:") #you'd missed the " at the beginning

changetoname=raw_input("What is the new name:")

list=list.replace(Changename, changetoname) #removed the '. They're the variables, not the strings 'Changename' etc that you want to replace.

print menulist

elif target=="9":

print"good bye" #excessive indenting

else: #this replaces the initial while

#do nothing if the initial input is not 1,2,3,4 or 9

print menulist
