Question

Which line of code will print Python is cool! on the screen?
print("Python is cool!")
print(Python is cool!)
print("Python is cool!)
print = Python is cool!

Accepted Answer

```python # This line of code prints the message "Python is cool!" to the screen print("Python is cool!") ``` ```python # main function that tests the print statement def main_test_print(): # Use case 1: Correct syntax with double quotes print("Python is cool!") # This should print "Python is cool!" to the screen without errors # Use case 2: Incorrect syntax examples which will not work as intended # print(Python is cool!) # This will raise a SyntaxError due to missing quotes # print("Python is cool!) # This will raise a SyntaxError due to unmatched quotes # print = Python is cool! # This will raise a SyntaxError and also incorrectly assigns a string to 'print' # Call the main_test_print function to execute the use cases main_test_print() ``` ∻Explanation∻ ⚹The correct line of code to print "Python is cool!" on the screen is `print("Python is cool!")`. The other lines contain syntax errors or incorrect assignment.⚹ ∻Step-by-step Instruction∻ ‖ ▪ ⋮ Define the main functions required here: print a message to the screen. ‖ ‖ ▪ ⋮ Choose to use the print function because it is the standard way to output messages in Python. ‖ ‖ ▪ ⋮ Define concrete use cases and testing cases for the print statement: when the correct syntax is used, it should print "Python is cool!" to the screen. ‖ ∻Time Complexity∻ ⚹The time complexity is not applicable here as we are not discussing an algorithm with multiple steps or iterations.⚹ ∻Space Complexity∻ ⚹The space complexity is not applicable here as we are not using any additional space or data structures.⚹
