+# 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`
+
+## Arguments
+
+The arguments must have numeric types.
+This function takes two arguments, `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).
+
+
+
+## Example
+
+```python
+print(pow(2,4))    # prints 16
+print(pow(10,-2))  # prints 0.01
+print(pow(4,3,5))  # prints 4
+```
