NEW QUESTION # 38
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)]
Answer:
Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: Python string indexing starts at 0.
Step 2: The last valid index of a string is len(text) - 1, not len(text).
Step 3: Python also allows negative indexing, where -1 means the last character.
Step 4: Replace text[len(text)] with text[-1] .
Correct code:
def get_last_character(text):
return text[-1]
Example:
print(get_last_character( " Python " ))
Output:
n
NEW QUESTION # 39
What advantage does an integrated terminal provide compared to using a separate terminal application?
Answer: D
Explanation:
An integrated terminal is built into a development environment or code editor. Its main advantage is that the developer can write code and run terminal commands in the same application.
This avoids switching back and forth between a separate terminal window and the code editor.
Therefore, the correct answer isC. Eliminates need to switch between applications.
NEW QUESTION # 40
Fix the off-by-one error in this function that should return the first 3 characters of a string.
def first_three(text):
return text[0:2]
Answer:
Explanation:
See the Step by Step Solution below in Explanation.
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
NEW QUESTION # 41
Which data type is the value 3.14 in Python?
Answer: C
Explanation:
The value 3.14 is afloatbecause it contains a decimal point.
Example:
type(3.14)
This returns:
< class ' float ' >
Python's built-in numeric types include integers and floating-point numbers. A value with a decimal part, such as 3.14, is treated as a floating-point number.
Therefore, the correct answer isB. Float.
NEW QUESTION # 42
What happens when the command python is entered in a terminal without a filename?
Answer: B
Explanation:
When the command python is entered in a terminal without a filename, Python starts aninteractive Python session, also called interactive mode.
In interactive mode, Python displays the primary prompt:
> > >
The user can then type Python statements directly, such as:
> > > 2 + 3
5
The official Python documentation explains that when commands are read from a terminal, the interpreter is in interactive mode and prompts for the next command.
Python does not automatically run the most recent file, open a file browser, or necessarily display an error when started this way.
Therefore, the correct answer isC. An interactive Python session starts.
