In the following example, we loop through a list of numbers, and use the variable digit to hold each number in turn: Strings in Python are considered “sequences” — they can be iterated over ...

First, you can’t just transport straight C for loops into Python. There has to be some concession ... was particularly interesting. That attempt used an odd feature to examine the interpreter ...

If you’ve ever written any Python at all, the chances are you’ve used iterators without even realising it. Writing your own and using them in your programs can provide significant performance ...

We use the same examples to demonstrate how to use for loops and while loops. However, for some situations, using while loops may be more appropriate than using for loops or vice versa. It is better ...

However, others use Python to streamline repetitive ... discover core programming tools such as loops and functions; and use variables to store, retrieve and calculate information.

you’ll study Python syntax and semantics and learn how to utilise core programming tools such as loops and functions and how to use variables to store, retrieve and calculate information.
