What do >> and << mean in Python?

Question

I noticed that I can do things like 2 << 5 to get 64 and 1000 >> 2 to get 250. 

Additionally, I can utilize >> on print: 

print >>obj, "Hello world"

What's going on here?

Answer 1

They are bitwise shift operators

From this docs:

x<<y

• Returns x with the bits shifted to the left by y places (and new bits on the right-hand-side are zeros). This is the same as multiplying x by 2**y.

x >> y

• Returns x with the bits shifted to the right by y places. This is the same as dividing x by 2**y
