Converting from a C double transferred in two hex strings

my very first day with Python.

I like to filter on a trace file generated by C. Each double from C is formatted in the file by two hex strings representing 32 bit of the 64 double.

e.g. 1234567890.3 (C double)
inside file:

0xb4933333
0x41d26580

How can I parse and combine it to further work with a Python float?

Thanks in advance
