我如何将以字节编码的 python 字典转换为 UTF-8 字典

Question

I have the following dictionary: pointsdict = {b'335139450613137430': b'1', b'704168692828864574': b'22'} where the first element is the user id and the second element is points. How could I change 335139450613137430's amount of points.

I have tried

decoded = pointsdict.decode()
decoded[userid] = pointstoset
pointsdict = decoded.encode()

and have received AttributeError: 'dict' object has no attribute 'decode' on the first line. How can I do this?

Thanks - Evan

Here is how you can store the decoded items into another dictionary:

pointsdict = {b'335139450613137430': b'1', b'704168692828864574': b'22'}

decoded = {}

for key in pointsdict.keys():
    decoded[key.decode('ascii')] = pointsdict[key].decode('ascii')

print(decoded)

Output:

{'335139450613137430': '1', '704168692828864574': '22'}

The code can be more compacted like this:

decoded = {key.decode('ascii'):pointsdict[key].decode(ascii) for key in pointsdict.keys()}
