Define a class named Timer that represents an amount of time in hours and minutes. The class should have two integer attributes: hours and minutes. The constructor should perform the following validation before assigning the values passed into the constructor:$1)$ Check if both arguments $($hours and minutes$)$ are integers. If not, raise a ValueError$\mathrm{.}2)$ Check if both arguments $($hours and minutes$)$ are positive. If not, raise a ValueError.Check if the value of minutes is between $0$ and $59.$ If not, raise a ValueError.Hint: The isinstance$)$ function can help verify the variable type.
