3 Programming constructs

3 Programming constructs

1. Iteration

   • Iteration is the repetition of a function in a program by using either condition controlled or count controlled statements.
     • In python this is achieved by using loops; WHILE (Condition) and FOR (Count)

2. Selection

   • Selection is used to make a decision based on information. This is often used in algorithms to repeat instructions or move to different parts of the program
     • In python , we use IF, THEN and ELSE statements when using selection.

3. Sequence

   • Sequence is the order of each line of code in a program. This needs to be in a logical order so the program can run line-by-line.
