Chapter 3: Conditionals & Exceptions (TL;DR)¶

• boolean expressions evaluate to either True or False
• relational operators (e.g., == or !=) compare operands according to "human" interpretations
• logical operators (e.g., and )combine boolean sub-expressions to more "complex" expressions
• the conditional statement (i.e., the if statement) allows controlling the flow of execution depending on some conditions
• a conditional expression is a short form of a conditional statement
• exception handling is also a common way of controlling the flow of execution, in particular, if we have to be prepared for bad input data
