NEW QUESTION # 15
Complete the function get_max(a, b) that returns the larger of two numbers. If they are equal, return either one.
def get_max(a, b):
# TODO: Return the larger of a and b
pass
Answer:
Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives two parameters: a and b.
Step 2: Compare the two values using an if statement.
Step 3: If a is greater than or equal to b, return a.
Step 4: Otherwise, return b.
Correct code:
def get_max(a, b):
if a > = b:
return a
else:
return b
Simplified correct code:
def get_max(a, b):
return max(a, b)
Example:
print(get_max(10, 20))
print(get_max(30, 15))
print(get_max(5, 5))
Output:
20
30
5
NEW QUESTION # 16
Which keyword moves a loop immediately to its subsequent iteration?
Answer: A
Explanation:
The Python keyword continue is used inside a loop to skip the rest of the current iteration and move immediately to the next iteration.
Example:
for number in range(5):
if number == 2:
continue
print(number)
Output:
0
1
3
4
When number is 2, the continue statement skips print(number) for that iteration and moves to the next loop cycle.
The official Python documentation states that the continue statement continues with the next iteration of the loop.
Therefore, the correct answer is C. continue.
NEW QUESTION # 17
What sequence of steps is required to execute a Python script from a text editor using the terminal on a Windows device?
Answer: D
Explanation:
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.
NEW QUESTION # 18
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
Answer:
Explanation:
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

def first_three(text):
return text[0:2]
Answer:

Explanation:
Step 1: Python string slicing uses this format:
text[start:stop]
Step 2: The start index is included.
Step 3: The stop index is excluded.
Step 4: To return the first 3 characters, start at index 0 and stop at index 3.
Correct code:
def first_three(text):
return text[0:3]
Simplified correct code:
def first_three(text):
return text[:3]
Example:
print(first_three( " Python " ))
Output:
Pyt
