IronPython: String is null or empty

Question

Ok, here are some easy points. PyBinding came with this script:

def IsNotNull(value):
    return value is not None

It is close, but what I want is this.

bool IsNotNullOrEmpty(string value) {
    return (value != null) && (value.Length > 0 );
}

EDIT WTF?

Someone gives the right answer "return value is not None and len(value) > 0", then deletes his post before I can say thank you. And what's left is a three people spouting off nonsense that doesn't even come close to giving the right result.

Answer 1

To check if a string is empty you would use len. Try this:

def IsNotNull(value):
    return value is not None and len(value) > 0

Answer 2

i think,

if IsNotNull(value) {

is equivalent to

if not value:

for strings. so i think the function is not necessary in python.

Answer 3

def IsNotNullString(s):
    return bool(s)

Rules of Python boolean conversion.

Answer 4

You should not be doing this in a function. Instead you should just use:

if someStringOrNone:
