WGU Foundations of Programming (Python) - E010 JIV1 Foundations-of-Programming-Python Prüfungsfragen mit Lösungen (Q20-Q25):

20. Frage
Which punctuation mark must appear at the end of an if statement line?

A. , comma
B. . period
C. : colon
D. ; semicolon

Antwort: C

Begründung:
In Python, an if statement line must end with a colon.
Example:
age = 18
if age > = 18:
print( " Adult " )
The colon : tells Python that an indented block of code follows. That indented block contains the statements that should run when the condition is true.
A semicolon, period, or comma is not used to begin the body of an if statement in Python.
Therefore, the correct answer is B. : colon.

21. Frage
Which terminal command is used to navigate to a different directory before running a Python script?

A. cd
B. goto
C. nav
D. move

Antwort: A

Begründung:
The command cd means "change directory." It is used in a terminal to move from one folder to another.
Example:
cd Desktop
After navigating to the correct folder, a Python script can be run with a command such as:
python script.py
Therefore, the correct answer isC. cd.

22. Frage
What distinguishes a terminal-based Python environment from other development environments?

A. Required internet connectivity for operation
B. Graphical user interface elements
C. Automatic file saving capabilities
D. Text-based command line interface

Antwort: D

Begründung:
A terminal-based Python environment uses atext-based command line interface. In this environment, the user types commands directly into a terminal or command prompt.
For example, a user may start Python by typing:
python
When Python is started from a terminal, the interpreter can run in interactive mode, where it displays prompts such as > > > and waits for the user to enter Python commands. The official Python documentation explains that when commands are read from a terminal, the interpreter is in interactive mode.
A terminal-based environment is not mainly identified by graphical user interface elements, internet connectivity, or automatic file saving.
Therefore, the correct answer isC. Text-based command line interface.

23. Frage
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?

A. filename[-3:]
B. filename[9:]
C. filename[:-3]
D. filename[:9]

Antwort: A

Begründung:
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:] .

24. Frage
In Python, what must follow the in keyword in a for loop?

A. A condition
B. A variable name
C. A number
D. An iterable object

Antwort: D

Begründung:
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.
