It is the left shift operator for Python.
A left shift operation, as the name says, move bits to the left.
Suppose you have 2 whose binary representation is 0010.
So
2<<2means to shift the bits twice to the left:0010 -> 0100 -> 1000
1000 is the binary representation for 8. Mathematically, left shifting is the same as multiplying a number by a power of 2 :
a<<b == a*2^b, but as the operation is done only by shifting, it is much faster than doing multiplications.
