Foundations-of-Programming-Python Exam Dumps and Practice Questions

In a Python for loop, the in keyword is followed by an iterable object, such as a list, string, tuple, dictionary, set, or range() object.

Example:

for name in ['Alice', 'Bob', 'Carol']:

print(name)

Here, ['Alice', 'Bob', 'Carol'] is the iterable object. Python's documentation explains that a for statement iterates over the items of a sequence or other iterable object.

Therefore, the correct answer isB. An iterable object.

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

The slice filename[-3:] extracts the last three characters from a string.

Example:

filename = 'document.pdf'

print(filename[-3:])

Output:

pdf

Another example:

filename = 'image.png'

print(filename[-3:])

Output:

png

Python strings support slicing, and negative indexes count from the end of the string.

Therefore, the correct answer isC. filename[-3:].

To run a Python script from the terminal, the terminal should be in the correct directory, or the full file path should be provided.

The cd command is commonly used to change directories before running the script.

Example:

cd Documents

python my_script.py

Python's documentation explains that Python can execute a script when the interpreter is called with a filename argument.

Therefore, the correct answer isC. Use the cd command to navigate to the script's directory.

Step 1: The function receives one string parameter named text.

Step 2: Python slicing can be used to reverse a string.

Step 3: The slice [::-1] means start at the end of the string and move backward by one character at a time.

Step 4: Return text[::-1].

Correct code:

def reverse_string(text):

return text[::-1]

Example:

print(reverse_string('hello'))

Output:

olleh
