Comparison Operators Lab

Introduction

We've learned about comparison operators, what they do and how to use them. We've also looked at logical and identity operators to compare elements. So, in this lab, let's practice our new skills by using these operators to get the result we would like out of each comparison.

Objectives

• Practice using comparison operators
• Practice using logical and identity operators

Instructions

Uncomment out the code in each cell as you start working on them. For example, when you begin on the first two examples in cell one, remove the first # on each line. Then, use the correct comparison operator to get the desired output, which you will find in a second comment at the end of the line feel free to remove this comment as well or keep it. Finally, Replace the [COMPARISON], with the correct operator. See the example below.

# boolean_compare = False [COMPARISON] True # True 
=> boolean_compare = False != True # True
OR
=> boolean_compare = False != True

Once uncommented, you can run the tests to see if your comparisons are working the way we would like them to be.

Remember the comparison operators are: ==, !=, <, >, <=, >=

# boolean_compare = True [COMPARISON] True # False
# boolean_compare2 = False [COMPARISON] True # False

# number_compare = 10 [COMPARISON] 10 # True
# number_compare2 = -20 [COMPARISON] 30 # True
# number_compare3 = 4 [COMPARISON] 5 # False

# string_compare = "stacy" [COMPARISON] "STACY" # True
# string_compare2 = "hey i love python!" [COMPARISON] "hi love python" # False
# string_compare3 = "this string is bigger than the other" [COMPARISON] "that is true" # True

In the next section, do not use either == or != operators

# list_compare = [0,0,0,0] [COMPARISON] [0,0,0] # True
# list_compare2 = [1,0,0] [COMPARISON] [0,0,0] # True
# list_compare3 = [0,0,0] [COMPARISON] [0,0,3] # False
# list_compare4 = [0,0,3,0] [COMPARISON] [0,0,3] # True
# list_compare5 = [0,0,4,0] [COMPARISON] [0,0,3] # False

Practicing Identity and Logical Operators

In this next section, use the identity and logical operators to get the desired output as you did in the examples above using the comparison operators.

Remember: the logcial operators are: and, or, & not and the identity operators are: is & is not

Use logical opertors for this section

# logical_compare = 2 [COMPARISON] [] # []
# logical_compare2 = [COMPARISON] [] # True
# logical_compare3 = 0 [COMPARISON] [] # 0
# logical_compare4 = True [COMPARISON] 2 # 2
# logical_compare5 = 2 [COMPARISON] 3 # 2
# logical_compare6 = [COMPARISON] True # False
# logical_compare7 = False [COMPARISON] 2 # False

Use identity opertors for this section

# a = []
# b = a
# identity_compare = {} [COMPARISON] {} # False
# identity_compare2 = a [COMPARISON] b # True
# identity_compare3 = b [COMPARISON] [] # True
# identity_compare4 = 9 [COMPARISON] 10 # True
# identity_compare5 = "Same" [COMPARISON] "Same" # False
# identity_compare6 = [1,3,4] [COMPARISON] [1,2,3] # False

Summary

Great work! After all that, there's nothing we can't compare, well I guess apples and oranges might still off the table. We practiced using comparison, logical, and identity operators in Python to compare elements of the same and different datatypes and or values. Going forward, there will be plenty of instances where we will need to compare elements. So, it is important to have a good understanding of how each of these operators works. Don't worry, as with all concepts in programming, the more we work with something the better we understand it.
