gdb python module read memory content

Question

Inside gdb to print the content at a particular memory address, I can ran the below command. It prints the content in hex

x <memoryaddress>

(gdb) x 299395816
0x11d86ae8: 0x0ec14153

I am using the gdb python module inside the gdb, what's the equivalent command to read the memory location with the gdb module inside my python script.

I guess inferior is what you want:

(gdb) python i = gdb.inferiors()[0]
(gdb) python m = i.read_memory(0x7fffffffe39c, 4) # an int32
(gdb) python print(m.tobytes())
b'\x01\x00\x00\x00'
