Conditionals and Control Flow

Question 1

Control Flow

Answer 1

Fill this in later

Question 2

Comparator

Answer 2

Check if a value is (or is not) equal to, greater than (or equal to), or less than (or equal to)

Eg.

1. Equal to (==)
2. Not equal to (!=)
3. Less than ()
4. Greater than or equal to (>=)

Question 3

Boolean Operators

Answer 3

Compare statements and result in boolean values. Three types:

Eg.

1. “and”, which checks if both statements are true
2. “or”; wchih checks if at least one of the statements is true
3. “not”, which fives the opposite of the statement

Question 4

Order of Operations for Boolean Operators

Answer 4

1. “not” is evaluated first
2. “and” is evaluated next
3. “or” is evaluated last.
   Anything in parentheses () is evaluated as it’s own unit (solve inside the parentheses first)

Question 5

Conditional statement syntax

Answer 5

a statement that executes some specific code after checking if its expression is true or false

Eg “if”, “Else”, “Elif”

Question 6

“IF/Else” pair? Example?

Answer 6

When running “If” as a conditional statement, “Else” is used to provide an option in case the “If” expression is not true.

Eg. “If this expression is true, run this indented code block; otherwise, run this code after the else statement.”

Question 7

“Elif” statement? Example?

Answer 7

Conditional statement; provides an alternative to an “if” statement in case it is false

Eg. “Otherwise, if the following expression is true, then do this.”

def greater_less_equal_5(answer):
    if answer > 5:
        return 1
    elif answer < 5:          
        return -1
    else:
        return 0

print greater_less_equal_5(4)
print greater_less_equal_5(5)
print greater_less_equal_5(6)
