Here, Python does a great job of telling you exactly what’s wrong. The messages “‘break’ outside loop” and “‘continue’ not properly in loop” help you figure out exactly what to do. If this code were in a file, then Python would also have the caret pointing right to the

What Chris said, with the additional argument that the tests should be run with the same Python executable and options as real code, so if you use -O to run your app, you should do it to run your tests. (Personally, I’m not convinced, and I’ve never used -O to run

This is of uttermost importance in Python. Inheritance delegation occours automatically, but if a method is overridden the implementation of the ancestors is not considered at all. So, if you want to run the implementation of one or more of the ancestors of your

There are other comparison operators that we can use. So, in addition to equals equals, there’s the opposite, which is not equal, we write not equal with an exclamation point equals. So, that’s true if L is not equal to. So, if the value of L is not equal to the

Normally characters enclosed in quotes (” “) are treated literally, not as any type of code. This means that when you enter “5 + 4” python will see it as a text string of 5 + 4 (i.e not math). Python will not see it as a math problem that equals 9. If you enter 5 + 4

long data type Python 2 had separate int and long types for non-floating-point numbers. An int could not be any larger than sys.maxint, which varied by platform.Longs were defined by appending an L to the end of the number, and they could be, well, longer than ints. to the end of

In Python and many other programming languages, the equality sign means ‘to assign a value’.However, when using conditionals, we often want to check if a condition is satisfied.In this case, we use a double equality sign(==).Moreover, 5 is a number, not a

A point not mentioned in any answer yet (but which could be added to almost any of them, which is why I’m mentioning it here): some of these languages use ! for NOT already, so != is slightly more natural than , or the other ASCII-only operators from the

There should not be space between the two-symbol Python substitutes. Notice that the obvious choice for equals, a single equal sign, is not used to check for equality. An annoying second equal sign is required. This is because the single equal sign is already
