How to change the number size?

Question

Python

If you try to store a number in an N-bit variable that requires more than N bits for its record, then the high-order bits of the number will be cut off. For example, if you store the value 10 in a two-bit unsigned variable, then the value of this variable will be equal to 2.
I did this:
A = int('10', 2)
print A#Output : 2
Is this correct, or is it just a coincidence?

Answer 1

two bits will either be 00 or 01 or 10 or 11. This way you will only get 0, 1, 2, 3 in decimal.

Answer 2

This is the conversion of the binary number 10 to decimal.
