Object-Oriented Python
Challenge Task 1 of 1 Alright, here's a fun task!
Create a function named combiner that takes a single argument, which will be a list made up of strings and numbers.
Return a single string that is a combination of all of the strings in the list and then the sum of all of the numbers. For example, with the input ["apple", 5.2, "dog", 8], combiner would return "appledog13.2". Be sure to use isinstance to solve this as I might try to trick you.
Important: In each task of this code challenge, the code you write should be added to the code from the previous task.

Then if the item is a string we would append it to the string we want to return. If it is a number we would sum it to the number we would return.
Then we return both the strings and the summed numbers
def combiner(list):
string = ''
summ = 0
for item in list:
if isinstance(item,str):
string+=item
elif isinstance(item,(int,float)):
summ+= item
return string+str(summ)

You can us isinstance method for this and create a if else statement. Also don't forget to change num into int before adding that to your final string
