Conditions and Boolean Logic

Learners use comparisons to ask True/False questions, trace if, elif and else to see which single branch runs, and combine conditions with and, or and not using truth tables. A reading-club badge program shows why the order of an elif chain matters and how boundary values reveal decision bugs.

What learners will discover

  • Evaluate comparisons to True or False and tell == (compare) from = (store).
  • Trace if, elif and else statements and predict which branch runs, including at boundary values.
  • Combine conditions with and, or and not, and evaluate them using a truth table.
  • Order the branches of an elif chain correctly and choose boundary tests to find decision bugs.
