Quiz: What would this code produce if we were to copy-paste it in a code editor and run it?
def get_greeting(name):
print("Hey, " + name)
greeting = get_greeting("Andy")
print(greeting)
Options:
A: It would print:
Hey, Andy
B: It would print:
Hey, Andy
Hey, Andy
C: It would print:
None
Hey, Andy
D: It would print:
Hey, Andy
None
Important Note:
Do not use an actual code editor to get the answer! It would defy the whole purpose of the quiz!
Instructions:
Pick your answer and assign variable answer
in the code editor with that answer.
For example, if you think the answer to the quiz is B
, write answer = "B"
in the code editor and press Validate Solution!
.
The core challenge of this problem is understanding the behavior of the Python function and its return value. Specifically, we need to determine what the function get_greeting
returns and how it interacts with the print
statements.
To solve this problem, we need to break down the code step-by-step:
get_greeting
takes a parameter name
and prints "Hey, " followed by the value of name
.get_greeting("Andy")
is called, it prints "Hey, Andy".get_greeting
does not have a return statement, so it implicitly returns None
.greeting
is assigned the return value of get_greeting("Andy")
, which is None
.print
statement prints the value of greeting
, which is None
.Here is a step-by-step breakdown of the algorithm:
get_greeting
with a parameter name
.name
.get_greeting
with the argument "Andy".greeting
.greeting
.def get_greeting(name):
# Print the greeting message
print("Hey, " + name)
# Call the function and assign its return value to 'greeting'
greeting = get_greeting("Andy")
# Print the value of 'greeting'
print(greeting)
The time complexity of this code is O(1) because it involves a constant number of operations regardless of the input size. The space complexity is also O(1) as it uses a fixed amount of memory.
There are no significant edge cases for this problem since it involves a simple function call and print statements. However, if the function were to handle different types of input, we would need to consider those cases.
To test this solution, we can run the code and observe the output. The expected output is:
Hey, Andy
None
We can also test with different names to ensure the function behaves as expected.
When approaching such problems, it's essential to understand the behavior of functions and return values in Python. Practice by writing small functions and observing their outputs. This will help you develop a deeper understanding of how Python handles function calls and return values.
In this problem, we explored the behavior of a Python function and its return value. By breaking down the code step-by-step, we determined that the function prints a greeting message and returns None
. This understanding allowed us to predict the output correctly.
