Question

I’m doing some work with the Windows registry. Depending on whether Python is running as 32-bit or 64-bit, certain key values will be different. How can I detect whether Python is running as a 64-bit application or as a 32-bit application? (I’m not interested in detecting 32-bit/64-bit Windows – just the Python platform.)

Answer 1

import platform
platform.architecture()

From the Python docs:

Queries the given executable (defaults
to the Python interpreter binary) for
various architecture information.

Returns a tuple (bits, linkage) which
contain information about the bit
architecture and the linkage format
used for the executable. Both values
are returned as strings.
