您如何使用添加到字典中？

Question

I've almost at my end goal with this. I want the user to type in a list of names and then the position of the word to be saved in the dictionary if the word is not already been saved. For example Ali, Dan, Martin, Ali will read 1 2 3 1 .

Names= input("Type all names you want to include: ")
##str.casefold
Names = Names.split()
AllWords = len(Names)
dict = {}
pos=0
for j in enumerate(Names):
    for j in range(AllWords):
        if Names not in dict:
          dict.update(key,Names)
print(Dictionary)

Expected output would be:
Matt Mike Jerry Jon Sarah Matt 1 2 3 4 5 1 #names and positions

Answer 1

您可以简单地执行以下操作，以便在现有或空字典中添加更多键值对。

Dictionary[key] = value

Answer 2

字典没有append(value)方法，请改用update({key: value}) 。

Answer 3

As far as i know Dictionaries in python does not have any method called append , instead make use of update

dict.update({key:value})  or dict[key] = value

in the second case if key is not present it will add a new entry, if key is there it will update the value corresponding to that key.

Hope it helps.
