"&" and "and" operator in python hHHHeelppp

Question

ls = []
for i in range(17):
ls.append(i * 3)
m = [i & 1 for i in ls]
print(m)
Output: [0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]

ls = []
for i in range(17):
ls.append(i * 3)
m = [i and 1 for i in ls]
print(m)
output: [0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0]

from sample above, what's the difference between "&" symbol and "and" statement in python?
Also, why it has 0,1,0,1 etc. elements in sample 2? It supposed to be 0,1,1,1,1...]
Thank you

Answer 1

& is a binary operation
and is like or

1 & 17

10001
00001
----------
1
16 & 1
10000
00001
----------
0

16 and 1
16 ,1 are true (not 0) so 16 and 1 is true

Answer 2

& is bitwise AND operator
&& Is logical operator also known as logical AND or what you calling as and

Bitwise works on binary digits while the logical one works on boolean expressions like true or false.

Answer 3

And yes the outputs are wrong
sample 1 output is [ 0 1 0 1 0 1...]
And sample 2 output is [0 1 1 1 1 1 ...]

Answer 4

As everyone says "&" is and bitwise Operator "and" is logical Operators...

Look at the answer of Frogged mam
1&17 gives the bit of 17 at zeroth index which is 1.
And if you use left shift Operator then it will give the bits at the position .means look like this
(1<<position)&17(position is a varible)
Give then bits of 17 on the position variable...
Thats all about & Operator

Now lets see "and" operators ..
Consider we have to print the values from 0 to 10 which is both divisional by 3 and 5 ..
So how we code? The basic approach that we get is that we first use a loop and take a condition the value % 3 and 5 then print the values
The pseudo code will looks like this
For value in range(10)
If value%3==0 and value%5==0:
Print(value)
and operator is used to combine the two more conditions
It will return true only when both condition are true..

So bitwise Operator works in terms of bits
And operator is used to combine two of more conditions....
