So, I decided to do some challenge, I was surprised I was been asked shhhh I never seen B4. This one caught my fancy:
x = 5 print (x>>2<<x) I did it on the code playground with the result being 32. Can someone please explain what '<<' and '>>' means?

They are Bitwise Operations. Bitwise Left shift and bitwise Right shift.

5 >> 2 is 1
1 << 5 is 32.

Since both the operators have the same precedence then according to associativity, we solve from left to right.
x>>2 = 5>>2
It means binary 5 has been shifted to right by 2 digits. I'm using 8 bits for representation.
0000 0101 -> 5
0000 0001 -> 1 // after shifting right by 2 digits. So you have the result 1. Now binary 1 is shifted to left by 5 digits because 1<<x which is 1<<5.
0010 0000 -> 32
