Specify Quantity: 10
10

Example 2.2, Page No 31

iNo = raw_input("Specify Quantity: ")
print "You entered", iNo

specify quantity22
You entered 22

Example 2.3, Page No 32

iNo = raw_input("specify quantity: ")

print "INVOICE"
print "========"
print "Quantity: ", iNo
print "Price per Unit: ", dUnitPr
