什么是CPP reinterpret_cast的Python等价物

Question

I got stuck in a trivial problem of reinterpret_cast casting operator. Basically, in CPP, I have a float variable which is used to create a uint32_t variable using reinterpret_cast as shown below-

float x = 2.2949836e-38;
uint32_t rgb = *reinterpret_cast<uint32_t*>(&x);
printf("rgb=%d", rgb); // prints rgb=16377550

I want to achieve the same in python. Please note that conventional int casting isn't producing the expected result.

Answer 1

You can use pack , unpack from struct module:

from struct import pack, unpack

b = pack('f', 2.2949836e-38)
print(unpack('i', b)[0])

Prints:

16377550
