Python's equivalent to null-conditional operator introduced in C# 6

Question

Is there an equivalent in Python to C# null-conditional operator?

System.Text.StringBuilder sb = null;
string s = sb?.ToString(); // No error

Answer 1

Well, the simplest solution would be:

result = None if obj is None else obj.method()

---

But if you want the exact equivalent having the same thread safety as the C#'s Null-conditional operator, it would be:

obj = 'hello'
temp = obj
result = None if temp is None else temp.split()

The trade off is that the code isn't really pretty; Also an extra name temp gets added to the namespace.

Another way is:

def getattr_safe(obj, attr):
    return None if obj is None else getattr(obj,attr)

obj = 'hello'
result = getattr_safe(obj,'split')()

Here, trade-off is the function calling overhead, but much clearer code, especially if you are using it multiple times.
