+# Python 'pow(x,y)'
+
+pow(x, y[, z]) is a built in function in Python 3 to calculate x to the power y and if z is present , returns x to the power y modulo [https://processing.org/reference/modulo.html] z
+
+#Argument 
+The arguments must have numeric types.
+It takes two argument x and y as well as three x,y and z.
+If z is present, x and y must be of integer types, and y must be non-negative.
+
+
+##Return
+If z is present it returns x to the power y modulo z.If only x and y are present it returns x to the power y (same as x**y).
+It is much faster than x**y % z.
+
+
+##Code Sample
+print(pow(2,4))  # prints 16
+print(pow(10,-2)) # prints 0.01
+print(pow(4,3,5)) #prints 4
