Hi, i want to save an array my_array = [1,2,3,4,5] and replace a element from my_array with a value, but i don’t want to change my principal array.
For example,

my_array = [1,2,3,4,5]
replace 2 for 8
new_array = [1,8,3,4,5]

Then, if print my_array = [1,2,3,4,5] and new_array = [1,8,3,4,5]
Is there a function that does that?

Thanks!
