I’m stuck on this weird thing in Python where changing one thing messes with another. But with other variables it works fine.
How do I fix this?
example = [1, 2, 3,4,5]
new = example
new[3] = 6
print(example)
Which outputs [1, 2, 3, 6, 5] instead of [1,2,3,4,5]
>Solution :
When you set new = example, you’re essentially making both of them refer to the exact same memory location. Hence any change made to one will be seen in the other.
We can correct this with
new = example[:]
Although in some cases you need to
import copy
new = deepcopy(example)
