What is the correct thinking about the syntax? 

[] and {} or 1

Result of this code is 1 I am not sure how to explain this example.

I tried understanding [] and {} and this return []

  • One should also point out [operator precedence](https://docs.python.org/3/reference/expressions.html#summary) and Python's left-to-right evaluation. – Daniel Lenz Sep 03 '19 at 22:03

In order of operations, and comes before or, so the effective statement is 

([] and {}) or 1

bool([]) is False.

bool({}) is False.

Therefore, [] and {} is [].

Finally, [] or 1 is 1.
