How to get value of REG_DWORD variable from registry

Question

I've created a variable in the Windows registry (via regedit), and want to get the value of my variable which has a REG_DWORD type. I use this code to get the value:

def get_DWORD_val(): 
    from winreg import ConnectRegistry, HKEY_LOCAL_MACHINE, OpenKey, QueryValue, REG_EXPAND_SZ, REG_SZ
    try:
           root = ConnectRegistry(None, HKEY_LOCAL_MACHINE)
           print("---1")
           root_key = OpenKey(HKEY_LOCAL_MACHINE, r'SOFTWARE\Python', 0, KEY_READ)
           print("---2")
           [Pathname,regtype]=(QueryValue(root_key,"Ver_Tokenlog"))

    except WindowsError:
        return ["Error"]

    return Pathname

Output :

---1
---2
['Error']

This error is thrown:

winerror 2 the system cannot find the file specified

I guess you meant QueryValueEx:

def get_DWORD_val(): 
    from winreg import ConnectRegistry, HKEY_LOCAL_MACHINE, OpenKey, QueryValueEx, QueryValue, REG_EXPAND_SZ, REG_SZ, KEY_READ

    root = ConnectRegistry(None, HKEY_LOCAL_MACHINE)
    print("---1")
    root_key = OpenKey(HKEY_LOCAL_MACHINE, r'SOFTWARE\Python', 0, KEY_READ)
    print("---2")
    Pathname,regtype = QueryValueEx(root_key, "Ver_Tokenlog")
    print(Pathname)
    print(regtype)


get_DWORD_val()

Output is:

---1
---2
