========================
Using Frequency Code: BB
What is the value of z when this code is finished executing?
x = 15 # x: 15
z = 0 # z: 0
if ( x < 10 ) :
z = 1
elif ( x < 20 ) :
z = 2
elif ( x < 30 ) :
z = 3
else:
z = 4
a. 4
b. 3
c. 2
d. 1
e. 0

===========================================
Boolean Operators (Continued)
For OR: the result of the boolean expression is TRUE
when EITHER operand is TRUE
otherwise the result is FALSE
// code for a value outside of a range
x = input ("Enter in an integer value")
if ( x < 10 ) or ( x > 20 ):
print ("The value is outside of the range")
Truth Table: (assume x and y are boolean values)
x y || x OR y x AND y
===========================================
true true || true true
true falue || true false
false true || true false
false false || false false
x = 1
y = 2
z = 3
if ( x < y ) and ( z < y ):
z = 7
