How to use python into gdbinit script

Question

I use gdbinit file to run few commands when gdb is init.

How can I use there python command? Instead using x/x $pc I want to print with binascii 10 bytes after $PC register.

How can I do that?

@alagner . No because I didn't understand how to take the value from python to gdb — yfr24493AzzrggAcom

Combining this answer with this one we end up with:

(gdb) x/10x $pc
0x55555555515d <main+8>:        0x48    0x8d    0x35    0xa0    0x0e    0x00    0x00    0x48
0x555555555165 <main+16>:       0x8d    0x3d

(gdb) source .gdbinit.py
488d35a00e0000488d3d

where .gdbinit.py contains:

import binascii
import gdb

i = gdb.inferiors()[0]
pc = gdb.parse_and_eval("$pc")
m = i.read_memory(pc, 10)
print binascii.hexlify(m)
