IsType (Reserved Word)
The istype reserved word is used to test the data type of value of a property, method, or variable and returns True is the type matches and False if the type is not as expected.
Example
When reading a value that has been saved to a GlobalDictionary element named 'myValue', the istype word is part an 'if' condition to determine the data type of the stored value and print the result.
if globalDict.Items["myValue"] istype double then
print("myValue is a double")
else
print("myValue is not a double");
