Question

This is probably a kinda commonly asked question but I could do with help on this. I have a list of class objects and I’m trying to figure out how to make it print an item from that class but rather than desplaying in the;

<__main__.evolutions instance at 0x01B8EA08> 

but instead to show a selected attribute of a chosen object of the class. Can anyone help with that?

If you want to just display a particular attribute of each class instance, you can do

print([obj.attr for obj in my_list_of_objs]) 

Which will print out the attr attribute of each object in the list my_list_of_objs. Alternatively, you can define the __str__() method for your class, which specifies how to convert your objects into strings:

class evolutions:     def __str__(self):         # return string representation of self  print(my_list_of_objs)  # each object is now printed out according to its __str__() method
