To fix the issue you can do this can be done easily as follows as a one liner: (considered to be pretty fast too) result = df.groupby('IDactivity')['GEOSTRING'].apply(lambda x:''.join(x.str[4])).tolist()

Appending an object to a list with python is throwing object memory address instead of the data inside the object

this will help When you print a single instance of MyPet, Python calls MyPet's __str__ method to get a string representation. When you print a list of objects, Python displays the result of calling repr on each element of the list. By default this will produce class MyPet:
def __repr__(self):
string = self.__name + ' ' + self.__animal_type + ' ' + str(self.age)
return string
__str__ == __repr__
class MyPet:
def __repr__(self):
return "MyPet(name='{}', animal_type='{}', age={})".format(self.__name,
self.__animal_type,
self.age)
def __str__(self):
string = self.__name + ' ' + self.__animal_type + ' ' + str(self.age)
return string
