Conditionals Recap

In this chapter, we learned how our program can decide what to do using conditions. We found out that:

• The if statement executes the following block of code if its condition is true.
• An if statement can be followed by an elif statement, which can have another condition that, if true, executes the elif statement's block of code.
• An if or elif statement can be followed by an else statement. The block of code for the else statement executes if all preceding if and elif conditions are false.
• After the first true condition, the corresponding block of code is executed, and the rest of the conditional is skipped.
• Comparisons are made using the following operators: == - Equals, != - Not equal, > - Greater than, >= - Greater than or equal to, < - Less than, <= - Less than or equal to.
• The block of code following a colon must be indented.
• There are two Boolean values: True and False.
• We can combine multiple conditions using the logical operators and and or.
• We can invert a condition using the not operator, changing True to False or vice versa.
• Nested conditions are those that are inside the block of another condition.
