behavior list of lists

[roym]

Hi Yoriz,

thanks for the reply. Oke, I see. So in your first example (which corresponds to my case), the values are changed in multiple places because the lists are the same, right?

Now if I consider the following example:

# define variable
a = 0

# create 1D list
lst = [0]*10
for i in range(10):
    lst[i] = a
 
# print the list
print(lst)
 
# assign value to element of list
lst[1] = 4
 
# print list after element assignment
print(lst)

I would expect that changing lst[1] results in a change of all entries in that list, because in this case lst[0] == lst[1] == lst[2] etc.. Why does it not update the entire list in this case?
