The Python equal operator (==) is used to compare two values, variables or expressions to determine if they are the same.

If the values being compared are the same, the operator returns True, otherwise it returns False.

The operator takes the data type into account when making the comparison, so a string value of "2" is not considered the same as a numeric value of 2.

When the operands are expressions, they are evaluated first, before the comparison is made.

The Python not equals operator (!=) is used to compare two values, variables or expressions to determine if they are NOT the same. If they are NOT the same, the operator returns True. If they are the same, then it returns False. The operator takes the data type into account when making the comparison so a value of 10 would NOT be equal to the string value "10" and the operator would return True. If expressions are used, then they are evaluated to a value of True or False before the comparison is made by the operator.

In Python, relational operators compare two values or expressions. The most common ones are less than (<), greater than (>), less than or equal to (<=), and greater than or equal to (>=). If the relation is sound, then the entire expression will evaluate to True. If not, the expression evaluates to False.

The not equals operator is a comparison operator that compares two values or expressions. It returns False if the values on either side are equal and True if the values on either side are not equal. As shown in the code above, the not equals operator can compare both numerical values and strings. It is formatted as (!=).

The Python and operator performs a Boolean comparison between two Boolean values, variables, or expressions. If both sides of the operator evaluate to True then the and operator returns True. If either side (or both sides) evaluates to False, then the and operator returns False. A non-Boolean value or variable will always evaluate to True when used with the and operator as long as they are assigned to a value.

The and operator is a logical operator that combines two boolean expressions. If both boolean expressions are true, then the and operator will return True. However, even if one expression is false, the operator will return False.

The Python or operator combines two Boolean expressions and evaluates to True if at least one of the expressions returns True. Otherwise, if both expressions are False, than the entire expression evaluates to False. The code above gives examples on how this works.

The Python Boolean not operator is used in a Boolean expression in order to evaluate the expression to its inverse value. If the original expression was True, including the not operator would make the expression False, and vice versa. For example, the statement 1>2 evaluates to False so adding the not operator will make not 1>2 evaluate to True.

The Python if statement is used to determine the execution of code based on the evaluation of a Boolean expression. If the if statement expression evaluates to True, then the indented code following the statement is executed. If the expression evaluates to False then the indented code following the if statement is skipped and the program executes the next line of code which is indented at the same level as the if statement.

Python uses conditional or if statements to run a segment of code only if a given boolean expression, or condition, is deemed true. If the expression evaluates as False, the code following the if statement will not run. In the code above, the method sweetSixteen() will only run if the conditional statement, myAge == 16, is true. Since the variable is equal to 16, the program will call sweetSixteen().

The Python else statement provides alternate code to execute if the expression in an if statement evaluates to False.

The indented code for the if statement is executed if the expression evaluates to True. The indented code immediately following the else is executed only if the expression evaluates to False. To mark the end of the else block, the code must be unindented to the same level as the starting if line.

else statements can be paired with if statements to provide a default control flow option. If the boolean expression of the if statement evaluates false, the code following the else statement will be run. For example, in the code above, since myAge is 15 not 16, the method sweetSixteen() will not be run. Rather the program will defer to the else statement and run happyBirthday().

Booleans are a data type in Python, much like integers, floats, and strings. However, booleans only have two values: True of False. Specifically, these two values are of the bool type. Since booleans are a data type, creating a variable that holds a boolean value is the same for other data types.

The Python elif statement allows for continued checks to be performed after an initial if statement. An elif statement differs from the else statement because another expression is provided to be checked just as with the initial if statement. If the expression is True the indented code following the elif is executed. If the expression evaluates to False the code can continue to an optional else statement. Multiple elif statements can be used following an initial if to perform a series of checks. Once an elif expression evaluates to True no further elif statements are executed.

A tryand except block can be used to handle error in code block. Code which may raise an error can be written in the try block . During execution, if that code block raises an error, the rest of the try block will cease executing and the except block code will execute.
