Activity 4
Workshop Resources
Try printing out the answers to the following expressions using print. If the results for any of these statements don’t make sense, please ask for help!
- 54 < (10 + 32)
- (37 / 5) != 7
- “Hello” + “World” == “Hello World”
- False == False
Challenge:
Try making your own expressions!
Fun Fact: Connecting Booleans with AND and OR operators
You can also connect boolean expressions together using the AND and the OR operator. Here’s a chart that describes what happens when we connect booleans together:
| Expression | Result |
|---|---|
| True and True | True |
| True and False | False |
| False and True | False |
| False and False | False |
| True or True | True |
| True or False | True |
| False or True | True |
| False and False | False |
To summarize, AND requires both boolean expressions to be true, while OR only requires one of the two Boolean expressions to be true. Here are some more examples:
- (5 < 8) and (9 != 10) produces True since both 5 is less than 8 and 9 is not equal to 10.
- (8 <= 2) or (“h” + “e” == “he”) produces True since “h” + “e” results in “he”, even though 8 is not less than or equal to 2.
- (6 != 2 * 3) or (8 < 2 * 4) produces False since both 6 not equal to 2 * 3, and 8 being less than 2 * 4, produce False.
What do you think the following expressions produce?
- (11-2 < 10) and (7+3 > 10)
- (True or 3 < 1) and (False or 3>1)
