& in python

Question

why is bool(1&2) false aren't both numbers true

Answer 1

& is a bitwise AND

1 in 4 bit binary is 0001
2 in 4 bit binary is 0010

0001
0010 &
--------
0000 = 0 = false

With a bitwise & both bits must be 1 to result in 1 otherwise the bit is 0

Answer 2

thanks for clearing that up @sayan I will sure do

Answer 3

thanks now I understood

Answer 4

@shaikh salman you mean bool(1&2) ,bool(1|2) ,I mean isn't "and" , and "or" in their literal form do normal logical operations ,while binary operators &,| do binary comparison , please correct me if I'm wrong I really thought I got it.

Answer 5

....
1 = 01
2 = 10
and(&) together go to "0"
....?
bool(1 and 2) perhaps?

bc & is binary operator

Answer 6

& is logical AND
as in AND gates

## Truth table..
A B Y=A.B
0 0 0
1 0 0
0 1 0
1 1 1

bool of 0 is false
bool of anything else is true(positive or negetive number)

other logical opeeators are
>> << ~ | ^
(google them)

Answer 7

1&2
-> 0001 & 0010
-> (0.0)(0.0)(0.1)(1.0)
-> 0000-> false
