Two array-bugs

emptytheory

I have come across what seems to be two bugs connected with the colon-notation for arrays.

1: It seems arrays defined using colon-notation stops being printable after being expanded more than once.

subArr = [0, 1][:0]
subArr[len(subArr)] = 1
subArr[len(subArr)] = 2
print(subArr)

This returns the following error: "Unknown type: 1433908896"
Printing the length of the array works, so it "is there", but cannot be printed.
Printing the list before the second expansion also works fine.

2: len() does not work with colon notation.

arr1 = [0, 1]
arr2 = [0]
arr3 = arr1[:len(arr2)]

This returns an error message telling me that the function len does not exist.
It can be bypassed by adding the following:

function len(x)
return len(x)

I hesitate a bit posting here, because I'm so new to programming that I'm seldom confident that the mistake is not with me, but this seems very strange.

I’ve encountered the same problem with colon notation. It’s best to do all your operations on a separate variable first (such as Len) then place that new variable in your colon notation.

I’ve also found anomalies if I didn’t spread these operations out on multiple lines. It ends up just clearing the array if I do too many operations in one line.
