Admittedly, C and Python work the same way, which is different to Go.
#include
int main(void) {
printf("%07x\n", 42);
printf("%0#7x\n", 42);
printf("0x%07x\n", 42);
return 0;
}
// Output
02a
0x0002a
0x02a

The '#' means you want the alternate format with the 0x prepended, and the
'7' means you want the number itself padded to 7 digits
x := fmt.Sprintf("%07x", 42) // 02a
y := fmt.Sprintf("%0#7x", 42) // 0x02a
z := fmt.Sprintf("0x%07x", 42) // 0x000
