Simultaneous comparison in Python
I want to make multiple comparisons at once, of the same type, in a Python program. For example, to check whether all of a certain group of strings are `in` a longer test string; or whether a specific variable is equal to any of some test values; etc.
I [discovered that these naive approaches won't work](https://software.codidact.com/posts/292968):
```python
if my_name and your_name in email:
print("The email is about both of us")
if cheese == "cheddar" or "edam" or "havarti":
print("Yum!")
```
The other Q&A explains why not. The question now is: *what should I do instead, in Python*? How can I write code that does these sorts of comparisons - and more generally, how can I *figure out how to* write the code?
And what if I want multiple possibilities on *both* sides of the comparison, or have the possibilities stored in a list (or other sequence)? Are there any special cases or other tricks?
