How will the content of the nested list change after overriding the variable

Determine what output will be obtained in the console after executing the following code. First, a list l is created, which is then included along with another list in a composite list t. Then the variable l is assigned a new value, different from the list. What will be printed?

l = [1, 2]
a = [5, 6]
t = [l, a]
l = "TEST"
print(t)
