Question

elif choice == "2":
    print("These are terms stored in the dictionary so far: ")
    for i in values_so_far:
        print(i)
    term = input("\nWhat term do you want me to add?: ")
    if term not in Dictionary:
        definition = input("\nWhat's the definition?: ")
        Dictionary[term] = definition
        print("\n",term,"has been added")
        Dictionary.append[term]
        values_so_far.append[term]
    else:
        print("\nThat term already exists! Try redefining it [option: 3]")

Answer 1

行Dictionary[term] = definition已添加了将term和definition关联到词典的键值对。 append不是为字典定义的方法。
