This is my point exactly. The C in Python was written by much more
careful and security aware programmers than I, checked by thousands.
This is why you almost never hear of security flaws or bugs in Python3.

Although made from C, Python3 has no pointers and has infinitly
expandable arrays and dictionaries, so no pointer exploits, no errant
pointers, no ininitialized pointers, and no buffer overflows. They pull
off RAM from the stack and the heap in the right way, and have garbage
collection, so memory leaks and the like are unlikely to occur by
accident. I can screw up a Python program in many ways, but assuming I
cleanse my inputs, few of those ways are a security risk.

In the hands of anything but a very careful and security-knowledgeable
programmer, writing Python3 is more secure than writing C. You could
think of Python3 as C with seatbelts and airbags, and a heck of an
inefficient transmission.
