3. Python Next Steps

The first lesson has a series of tasks designed to revisit the basic skills already covered. You will then use For loops and compare their use with While loops, before moving on to arrays (lists), which are introduced as a new data structure and are used in conjunction with For loops. Procedures and Functions with parameters are covered to help you understand the concept and benefits of modular programming. This unit is designed to take you right up to a point where a GCSE in Computer Science can pick up from and should provide ample experience of programming in order to confirm any decision to pursue Computing as a GCSE option.
