`if` condition with `as` keyword
Hi to everybody. I was looking for any resolution for my pain in PEP and Stack Overflow and can't find an answer. As well the similar ideas here are 13 years old and completely missed. I feel that I need to create a garbage code doing things like: ``` if myDict.get('spam'): print(myDict.get('spam')) ``` or ``` x = myDict.get('spam') if x is not None: print(x) ``` or ``` days = seconds // 86400 if days > 1: print(days) ``` and I want to use the `as` keyword instead i.e. ``` if myDict.get('spam') as x: print(x) ``` ``` if myDict.get('spam') as x is None: print(x) ``` ``` if (seconds // 86400) as days > 1: print(days) ```

Also, just to clearly demonstrate how the walrus operator could be used for the OP's examples: original: ``` if myDict.get('spam'): print(myDict.get('spam')) ``` walrus: ``` if (x := d.get("spam")): print(x) ``` original: ``` x = myDict.get('spam') if x is not None: print(x) ``` walrus: ``` if (x := d.get("spam")) is not None: print(x) ``` original: ``` days = seconds // 86400 if days > 1: print(days) ``` walrus: ``` if (days := seconds // 86400) > 1: print(days) ``` On Sun, Apr 26, 2020 at 9:04 AM Piotr Duda <duda.piotr@gmail.com> wrote:
