How to convert string bytecode to bytecode in python?-CodePudding

I have a string bytecode like this "b'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w=='"

and I want it as bytecode type like this b'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w=='

CodePudding user response：

There is no need for string manipulation here. The ast module can be used to convert the bytecode base64 str into a proper bytestring (bytes) object.

Example:

import ast

x = "b'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w=='"
out = ast.literal_eval(x)

Output:

>>> out
b'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w=='

>>> type(out)
bytes

You can use strip

data = '"b\'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w==\'"'
data = data.strip('\"')
print(data)

Output :

b'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w=='
