Input, Output and Variables

Learners see assignment as an instruction (work out the right side, then store), read user input with input() and convert it with int() and float(), format output with f-strings and choose valid, meaningful names. They finish by tracing complete programs, including the classic swap bug and its fix.

What learners will discover

  • Explain assignment: the right-hand side is worked out first, then stored, replacing the variable's old value.
  • Read user input with input() and convert it with int() or float() before doing maths.
  • Produce clear output with f-strings and choose valid, meaningful variable names.
  • Trace programs that read input and update variables, including swapping two values with a temporary variable.
