Python. Can someone please explain whats the problem at the if statement?

Question

I repeat this because no one said anything about that problem.

a = int(input())
while a != 1:
print (a)
if a & 2 = 0:
a = a // 2
else :
a = a * 3 + 1

print (a)

Answer 1

The modulo operator is %, not &. Also, ==, not =
