Fix the logic error in this function that should return the larger of two numbers. def find maximum (a, b): if a < b: return a else: return b - โโโ Correct Answer > def find_maximum(a, b): if a < b: return b else: return a Tip: Correctly returning the larger of two numbers using if-else
You can use either approach: Using a < b: if a < b: return b else: return a Using a > b: if a > b: return a else: return b Key point: The if condition and the corresponding return statements must align so the larger number is returned. Swapping the comparison requires swapping the return values accordingly. Which symbol begins a single-line comment in Python? // (double forward slash)
Which components are required in every Python while loop? A condition and an indented code block A variable and a return statement A counter and a break statement An iterator and a list - โโโ Correct Answer > A condition and an indented code block Which keyword is used to exit a loop prematurely in Python? return break stop end - โโโ Correct Answer > break In the code for item in my_list:, what does item represent? The index of the current element The current element being processed The length of the list The entire list - โโโ Correct Answer > The current element being processed Which Python data structure automatically prevents duplicate values from being stored?
List Tuple Dictionary Set - โโโ Correct Answer > Set Which Python data structure cannot be modified after creation? List Dictionary Tuple Set - โโโ Correct Answer > Tuple What must a developer do to run Python code written in a text editor? Save the file and use a Python interpreter. Press a run button within the editor. Upload the code to a web server. Convert the code to machine language first. - โโโ Correct Answer > Save the file and use a Python interpreter. What advantage does an integrated terminal provide compared to using a separate terminal application? Faster code execution speed
Text editor File explorer Debugger - โโโ Correct Answer > Python shell A program processes file names and extracts the last 3 characters representing the file extension. For example, files 'document.pdf' and 'image.png' would return 'pdf' and 'png', respectively. Which slicing approach would work for either of the provided files? filename[:9] filename[9:] filename[-3:] filename[:-3] - โโโ Correct Answer > filename[-3:] Which index position is returned when the string method .find('python') is applied to the string 'learning python programming'? 8 9 1 2 - โโโ Correct Answer > 9
Complete the function add_item(numeric_list, new_number) that takes a list of numbers and a new number, and returns a new list that appends the new number to the end of the list. For example, add_item([1, 2, 3], 4) should return [1, 2, 3, 4]. def add_item(numeric_list, new_number):
list
pass - โโโ Correct Answer > def add_item(numeric_list, new_number): numeric_list.append(new_number) return numeric_list Complete the function update_grade(grades, student, new_grade) that takes a grades dictionary, a student name, and a new grade, then updates that student's grade and returns the dictionary. For example, update_grade({"Alice": 85, "Bob": 90}, "Alice", 95) should return {"Alice": 95, "Bob": 90}. def update_grade(grades, student, new_grade):
A program needs to display only positive, non-zero numbers from a list containing a mixture of integer and decimal values. Which conditional statement should be placed inside the loop? if number > 0: if number != 0: if number < 0: if number >= 1 - โโโ Correct Answer > if number > 0: Complete the function double_number(num) that takes one number parameter and returns double that number. For example, double_number(5) should return 10. def double_number(num):
pass - โโโ Correct Answer > def double_number(num): return num * 2
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):
return "Hello " + name - โโโ Correct Answer > def greet_with_default(name="World"): return "Hello " + name Complete the function is_positive(number) that returns True if the number is greater than 0, and False otherwise. def is_positive(number):
pass - โโโ Correct Answer > def is_positive(number): return number > 0 Write a complete function calculate_discount(price, discount_percent) that calculates and returns the final price after applying a discount percentage. For example, calculate_discount(75, 20) should return 60.0.
for char in password: if char.isalpha(): has_letter = True elif char.isdigit(): has_number = True
has_number pass - โโโ Correct Answer > def password_strength(password): if len(password) < 8: return "Weak" has_letter = False has_number = False for char in password: if char.isalpha(): has_letter = True elif char.isdigit(): has_number = True if has_letter and has_number:
return "Strong" else: return "Weak" Write a complete function convert_temperature(celsius) that converts Celsius to Fahrenheit using the formula: F = C * 9/5 + 32. For example, convert_temperature(0) should return 32.0. def convert_temperature(celsius):
pass - โโโ Correct Answer > def convert_temperature(celsius): return celsius * 9 / 5 + 32 Fix the indexing error in this function that should return the last character of a string. def get_last_character(text): return text[len(text)] - โโโ Correct Answer > def get_last_character(text): return text[-1]
