How can I learn type of argument at function in Haskell ? In python, we have type ( ) function.
Ex:
in func;
if type ( a ) == Int
do <something>
But, I don’t know how I can manage that wish in Haskell ?
You don’t need this since Haskell is statically typed and all types are known at compile time. In case of polymorphic functions like
length :: [a] -> Int(Calculate the length of a list of elements of typea), there is no way to find out about the type of the argument, since you specified with the type that any argument type fits.
