在Python中将字符串转换为列表字典

Question

So in my python script I have the following dictionary, except it's listed in string form:

{'MSVCRT.dll': ['atoi'], 'KERNEL32.DLL': ['VirtualFree', 'ExitProcess', 'VirtualProtect', 'LoadLibraryA', 'VirtualAlloc', 'GetProcAddress'], 'SHLWAPI.dll': ['PathFileExistsA'], 'USER32.dll': ['wsprintfA']}

I however would like to have this code as a dictionary of lists, as it clearly is. I tried the following code in orderto attempt to convert the string:

    try:
        dictimports = ast.literal_eval(stris)
        print(dictimports)
    except:
        print("dict convert failed")

However it hits the except everytime :(

So to reiterate, I would like the keys to be say 'KERNEL32.DLL', and then those keys to have the list as the contents of the values, so have a list with the values ['VirtualFree', 'ExitProcess', 'VirtualProtect', 'LoadLibraryA', 'VirtualAlloc', 'GetProcAddress'] in this instance.

Answer 1

stris = {'MSVCRT.dll': ['atoi'], 'KERNEL32.DLL': ['VirtualFree', 'ExitProcess', 'VirtualProtect', 'LoadLibraryA', 'VirtualAlloc', 'GetProcAddress'], 'SHLWAPI.dll': ['PathFileExistsA'], 'USER32.dll': ['wsprintfA']}

stris is a dictionary. what seems to be the problem?

type(stris)

dict

stris.keys()

dict_keys(['MSVCRT.dll', 'KERNEL32.DLL', 'SHLWAPI.dll', 'USER32.dll'])

if your stris is a string - in which case you'd have

stris  = "{'MSVCRT.dll': ['atoi'], 'KERNEL32.DLL': ['VirtualFree', 'ExitProcess', 'VirtualProtect', 'LoadLibraryA', 'VirtualAlloc', 'GetProcAddress'], 'SHLWAPI.dll': ['PathFileExistsA'], 'USER32.dll': ['wsprintfA']}"

and you will convert it to a dict

ast.literal_eval(stris)

{'MSVCRT.dll': ['atoi'], 'KERNEL32.DLL': ['VirtualFree','ExitProcess','VirtualProtect','LoadLibraryA','VirtualAlloc', 'GetProcAddress'],'SHLWAPI.dll': ['PathFileExistsA'],'USER32.dll':['wsprintfA']}

Answer 2

You could use eval() to convert the string to a dict.

The expression argument is parsed and evaluated as a Python expression

eval(stris) will execute the executions given as string an in your case return the parsed dictionary.

But be aware of this: Using python's eval() vs. ast.literal_eval()?
