You can use ldd on the python executable like so:
$ ldd /usr/bin/python
linux-vdso.so.1 => (0x00007fff6bbb4000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00007f3b8562b000)
libdl.so.2 => /lib/libdl.so.2 (0x00007f3b85427000)
libutil.so.1 => /lib/libutil.so.1 (0x00007f3b85223000)
libssl.so.0.9.8 => /lib/libssl.so.0.9.8 (0x00007f3b84fd1000)
libcrypto.so.0.9.8 => /lib/libcrypto.so.0.9.8 (0x00007f3b84c41000)
libz.so.1 => /lib/libz.so.1 (0x00007f3b84a29000)
libm.so.6 => /lib/libm.so.6 (0x00007f3b847a6000)
libc.so.6 => /lib/libc.so.6 (0x00007f3b84423000)
/lib64/ld-linux-x86-64.so.2 (0x00007f3b8586b000)
Notice the last line it indicates that the Python executable that I am
using is 64bit since it is pulling in the /lib64/ld-linux-x86-64.so.2
shared object. Your's may be the 32bit version.
