Python does not change the table items in the list after multiple assignments

the code is as follows:

student = ["c", "c", "c"]
a, b, c = student
print(student)

running result:
["centering," centering,"c"]

Mar.28,2021

>>> a, b, c = student[0], student[1], student[2]
>>> a
'c'
>>> b
'c'
>>> c
'c'

student itself does not change.
