How to write thus program in Python? (New to Python)

#4) input a list with different types of elements, make statistics on the number of various types

def datatype_statistic(ls):
    '''count the number of data types in a given list
    
    ---Parameters/Arguments---
        ls: a list with no more than 10 elements
        
    ---Output---
        stat_dict: a dict stores the statistic results
    
    ---Example---
        datatype_statistic([1,'2',3.5, 0.5, None, (1,1)]) = {
            'int': 1,
            'str': 1,
            'float': 2,
            'None'：1,
            'tuple': 1
        }
    '''
    
    
    return stat_dict

#pls use the example in the def document to test your function

def datatype_statistic(ls):
    my_list=len(ls)
    print("There are "+str(my_list)+" elements in this list" )
    print([type(item) for item in ls])
    stat_dict={'int':)
              'str':)
              'float':)
              'None':)
              'tuple':)}
    print(stat_dict)
