```
return balance 
- amount
```

Line breaks in Python or any language assumes that a new statement has started. Python is a dynamic language, so you can't simply check for compilation errors and end of a statement `;` is not used in Python. So in the above code `balance` is returned. The interpreter never reaches `- amount` which never throws a error.

To write a statement in multiple lines you use `\` character to notify the interpreter that the next line is a part of the current statement.

```
  return balance \  # Line below is a part of current statement.
  - amount
```

Also floating point is not a bug of python but the underlying platform handling numbers. It happens because it is the way the underlying c platform (on which python works in a sense) handles floating-point numbers. Floating point error is not a bug.

PS : Apologies. My intensions are not to criticize. Just sharing my opinions.

Thank you very much for the explanation.

I believe we are saying almost the same thing. Check the explanation in the article, I explicitly stated that "This is a good practice that could lead to a potential bug as only the expressions directly on the same line as the return gets evaluated."
