Write the below function, which takes a dictionary as an argument and writes it into a file whose name is also provided as an argument. However, the function must satisfy the following constraints: Each (key, value) pair must be written on a separate line All **numeric** keys must be written **first**, then keys which are **strings** must **follow**. You can assume that the dictionary only contains numeric and string based keys and values. All **numeric** keys must be sorted in **ascending** order, and all **string** based keys must be sorted in **ascending** order. The format for writing a key, value pair is: key -> value def dict2file(d, filename): return # Remove this line only when you answer this
