질문 # 26
Complete the function calculate_tip(bill, tip_percent) that calculates and returns the tip amount based on the bill and tip percentage.
For example, calculate_tip(50, 20) should return 10.0.
def calculate_tip(bill, tip_percent):
# TODO: Calculate and return the tip amount
pass
정답：
설명：
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives two parameters: bill and tip_percent.
Step 2: Convert the percentage into a decimal by dividing tip_percent by 100.
Step 3: Multiply the bill amount by that decimal value.
Correct code:
def calculate_tip(bill, tip_percent):
return bill * tip_percent / 100
Example:
print(calculate_tip(50, 20))
Output:
10.0
질문 # 27
Modify the function greet_with_default(name) by adding a default value of " World " to the name parameter so it can be called with or without an argument.
def greet_with_default(name):
# TODO: Add a default value of " World " to the name parameter
return " Hello " + name
정답：
설명：
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: A default parameter value allows a function to be called even when no argument is provided.
Step 2: The default value should be added in the function header.
Step 3: The parameter name should have the default value " World " .
Correct code:
def greet_with_default(name= " World " ):
return " Hello " + name
Example:
print(greet_with_default())
print(greet_with_default( " Alice " ))
Output:
Hello World
Hello Alice

Example:
for number in range(5):
print(number)
This loop runs 5 times. Python's documentation explains that the for statement iterates over items of a sequence or iterable.
Therefore, the correct answer isB. for loop.
질문 # 29
What sequence of steps is required to execute a Python script from a text editor using the terminal on a Windows device?
정답：A
설명：
To run a Python script from a text editor using the terminal on Windows, the file should first be saved with the .py extension. Then, the terminal is opened, and the script is executed using the Python command followed by the filename.
Example:
python filename.py
The official Python documentation explains that when the interpreter is called with a filename argument, it reads and executes the script from that file. On Windows, the python command can be used from a terminal after Python is installed and configured correctly.
Therefore, the correct answer is A. Save file > open terminal > type python filename.py.
