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)
```
