Erase whole array Python

Question

How do I erase a whole array, leaving it with no items?

I want to do this so I can store new values in it (a new set of 100 floats) and find the minimum.

Right now my program is reading the minimum from sets before I think because it is appending itself with the previous set still in there. I use .append by the way.

Answer 1

Note that list and array are different classes. You can do:

del mylist[:] 

This will actually modify your existing list. David's answer creates a new list and assigns it to the same variable. Which you want depends on the situation (e.g. does any other variable have a reference to the same list?).

Try:

a = [1,2] b = a a = [] 

and

a = [1,2] b = a del a[:] 

Print a and b each time to see the difference.

Answer 2

It's simple:

array = [] 

will set array to be an empty list. (They're called lists in Python, by the way, not arrays)

If that doesn't work for you, edit your question to include a code sample that demonstrates your problem.
