How to do safe cast in python

In c# I can safe cast by keyword as, e.g.:

string word=\"15\";
var x=word as int32// here I get 15

string word=\"fifte

Think not, but you may implement your own:

def safe_cast(val, to_type, default=None):
    try:
        return to_type(val)
    except (ValueError, TypeError):
        return default

safe_cast('tst', int) # will return None
safe_cast('tst', int, 0) # will return 0
