Quick Check: Python Conditional Expressions

Review

1. Which expression has valid Python conditional-expression syntax?

   A conditional expression follows the form value_if_true if condition else value_if_false.
2. What does a conditional expression produce?

   A conditional expression evaluates to one of its two value expressions.
3. When is the false-value expression evaluated?

   Python evaluates the condition first and then evaluates only the selected alternative.
4. Which is generally the better choice when each branch needs several statements?

   A normal if statement is clearer when the branches need blocks of work rather than one selected value.
5. What should you do when a conditional expression becomes hard to read?

   Readable Python matters more than forcing a compact expression.
