58. Frage
What happens when theRunbutton is clicked in a Python development environment?
Antwort: C
Begründung:
In a Python development environment, clicking theRunbutton generally executes the currently open Python script or selected code.
For example, if the current script contains:
print( " Hello, Python! " )
clickingRunexecutes the script and displays the output:
Hello, Python!
In Python's IDLE environment, theRun Modulecommand runs the current module. The Python documentation describes IDLE as Python's editor and shell and includes a Run menu for running Python code.
The Run button does not simply open a file browser, save the file without execution, or convert Python code into another programming language.
Therefore, the correct answer isB. The currently open Python script is executed.
59. Frage
Which type of loop repeatedly checks a condition to determine whether to continue?
Antwort: B
Begründung:
Awhile looprepeatedly executes a block of code as long as its condition remains true.
Example:
count = 1
while count < = 3:
print(count)
count += 1
In this example, Python checks the condition count < = 3 before each loop iteration. If the condition is true, the loop continues. When the condition becomes false, the loop stops.
A for loop is usually used to iterate over a sequence, such as a list, string, or range. Python does not have a built-in repeat loop construct.
Therefore, the correct answer isB. while loop.
60. Frage
What must be consistent within a Python code block for the code to run without syntax errors?
Antwort: A
Begründung:
In Python, indentation is used to group statements into a code block. A block must have a consistent indentation level so Python can correctly understand which statements belong together.
For example:
if True:
print( " Hello " )
print( " World " )
Both print() statements belong to the same if block because they use the same indentation level.
If indentation is inconsistent, Python can raise an IndentationError or TabError.
Therefore, the correct answer isB. Indentation level.
61. Frage
Write a complete function password_strength(password) that returns " Strong " if the password is at least 8 characters long and contains both letters and numbers, " Weak " otherwise.
For example, password_strength( " abc123def " ) should return " Strong " .
def password_strength(password):
# TODO: Return " Strong " or " Weak " based on password criteria
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
# TODO: Add your return logic here based on has_letter and has_number
pass
Antwort:
Begründung:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: First, check the password length using len(password).
Step 2: If the password has fewer than 8 characters, return " Weak " immediately.
Step 3: Create two Boolean variables: has_letter and has_number.
Step 4: Loop through each character in the password.
Step 5: Use .isalpha() to check for letters and .isdigit() to check for numbers.
Step 6: If the password contains both at least one letter and at least one number, return " Strong " .
Step 7: Otherwise, return " Weak " .
Correct code:
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 "
Example:
print(password_strength( " abc123def " ))
print(password_strength( " abcdefgh " ))
print(password_strength( " 12345678 " ))
Output:
Strong
Weak
Weak
62. Frage
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.
def calculate_discount(price, discount_percent):
# TODO: Calculate and return the final price after discount
pass
Antwort:
Begründung:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives the original price and the discount_percent.
Step 2: Convert the discount percentage into a decimal by dividing by 100.
Step 3: Subtract the discount from 1 to find the remaining price percentage.
Step 4: Multiply the original price by the remaining percentage.
Correct code:
def calculate_discount(price, discount_percent):
return price * (1 - discount_percent / 100)
Example:
print(calculate_discount(75, 20))
Output:
60.0
