How to print a specific attribute of multiple objects in Python

Question

I'm trying to iterate through a list of objects and print out a specific attribute of which they all have.

for example:

class egg:
    def __init__(self, spam):
        self.spam = spam

x1=egg(1)
x2=egg(2)
x3=egg(3)

eggSalad=[x1,x2,x3]
print(eggSalad[:].spam)

I would like to get:

1
2
3

but recieve the following error:

AttributeError: 'list' object has no attribute 'utility'

I understand why the error is occurring but don't understand how to achieve my goal.

What is the correct way to go about doing this?
