Question

a = 0 and 1 or 0
b = 0 and 0 or 1
c = 1 or 0 and 0
d = 0 or 1 and 0
print(a, b, c, d)

why output is this:
0 1 1 0

Answer 1

This is just basic logical operation solving, I am not sure, which part you did not understand.

First you need to know 2 things:
and has higher operation precedence than or.
You propably know, that any zero values represent False (0=False), and any nonzero values represent True (1=True).

Then those should be easy to solve
a = 0 and 1 or 0
First we want to know what is 0 and 1, that's 0.
a = 0 or 0
Then we want to know what is 0 or 0, that's 0.
a = 0

b = 0 and 0 or 1
b = 0 or 1
b = 1

c = 1 or 0 and 0
c = 1 or 0
c = 1

d = 0 or 1 and 0
d = 0 or 0
d = 0

Like you propably noticed, and was always solved before or.

Answer 2

a = 0 and 1 or 0
b = 0 and 0 or 1
c = 1 or 0 and 0
d = 0 or 1 and 0
print(a, b, c, d)

why output is this:
0 1 1 0
