如何更新列表中的项，它是字典中键的值？

Question

So its something like this:

{'golden': [1], 
'crazy': [1]}

and then probably update it to

{'golden': [2], 
'crazy': [2]}

I just want to know how I can access that list in the value of the dictionary and then change it from 1 to 2.

Answer 1

You can access dict items even if they are lists the same way, so

dict['golden']

returns that array. If you want to set the first item in the array to 0, you would do it the same way you would normally update list values:
dict['golden'][0] = 2

Or append simpmly by doing
dict['golden'].append(2)

If you never add to that list though, it doesn't make sense for your dict to be list objects, it might as well just be an integer

Answer 2

You can do something like this:

your_dict['golden'][0] += 1
your_dict['crazy'][0] += 1
