# LAB 3

## Lab Description:

The Purpose of this lab was to create a menu that is linked to list of expressions that when selected executes the expressions chosen. Like Lab 2 this Lab starts off by assigning number of options to expressions to be executed.The difference is that these expressions,being locally in a while statement, are conditionally chained.

## Code:

option = 1
option = 2
option = 3
option = 4
option = 5
option = 6
option = 7
print ("1-The sum x + y")
print ("2-The difference x  y")
print ("3-The product x * y")
print ("4-The quotient x/y")
print ("5-The remainder x%y")
print ("6-Whether x is less than, equal, or greater than y")
print ("7-Exit")
option = input ("Enter option # from menu to perform operation or Enter number (7) to Exit")
while option <7 :

if option == 1:
X = input ("Enter X ")
Y = input ("Enter Y ")
Z = X + Y
print "X + Y = ", Z
print option
(option == 2 );
option = input ("Enter option # from menu to perform operation or Enter nember (7) to Exit")
#Print option

elif option == 2:
X = input ("Enter X ")
Y = input ("Enter Y ")
Z = X - Y
print "X - Y = ", Z
option = 3
print option
(option == 3) ;
option = input ("Enter option # from menu to perform operation or Enter number(7) to Exit ")
#Print option

elif (option == 3):
X = input ("Enter X ")
Y = input ("Enter Y ")
Z = X * Y
print "X * Y = ", Z
option = 4
print option
(option == 4) ;
option = input ("Enter option # from menu to perform operation or Enter number (7) to Exit ")
#Print option

elif (option == 4):
X = input ("Enter X ")
Y = input ("Enter Y ")
Z= X / Y
print "X / Y =  ", Z
option = 5
print option
(option == 5) ;
option = input ("Enter option # from menu to perform operation or Enter number (7) to Exit ")
#Print option

elif (option  == 5):
X = input ("Enter X ")
Y = input ("Enter Y ")
Z = X % Y
print "X % Y = Z ", Z
option = 6
print option
(option == 6) ;
option = input  ("Enter option # from menu to perform operation menue or Enter number (7) to Exit ")
#Print option

elif  (option == 6) :
X = input ("Enter X ")
Y = input ("Enter Y ")
if  X  Y :
print 'X is greater than Y'
else :
print 'X and Y are equal'
option = input ("Enter option # from menu to perform operation or Enter number (7) to Exit")
if    (option == 7)  :
print ("goodbye")
