What is the correct sequence of blocks in a conditional statement that uses all three components: if, elif, and else?
- if, elif, else
- if, else, elif
- else, if, elif
- elif, if, else
In Python, the correct sequence in a conditional statement that uses all three components is if, followed by one or more elif blocks, and finally, an optional else block.
What potential issue might arise from relying on the value of the name attribute in a module that is dynamically imported using functions like import()?
- Circular Import
- ImportError
- ModuleNotFoundError
- NameError
Relying on the name attribute in a dynamically imported module can lead to circular imports. Circular imports can create a situation where two or more modules depend on each other, causing potential issues and making the code harder to maintain.
The Python type(_______) would return .
- Text
- character
- str
- string
The Python 'type()' function checks the type of an object. To return '', you would use 'type(str)'.
A colleague is facing an ImportError when trying to import a package. Upon checking, you notice the package directory lacks a certain file, making Python not recognize it as a package. Which file is missing?
- init.py
- main.py
- package.py
- setup.py
The 'init.py' file is missing. This file is required in Python package directories for package recognition and proper importing.
Which operator will return True if both the operands are true?
- and
- not
- or
- xor
The 'and' operator in Python returns True if both of its operands are true. It performs a logical AND operation. For example, True and True evaluates to True, while True and False evaluates to False.
When dealing with file I/O, the _______ statement is often used to ensure that the file is properly closed after its suite finishes.
- close
- open
- try-finally
- with
When dealing with file I/O, the try-finally statement is often used to ensure that the file is properly closed after its suite finishes, even if an exception is raised.
Given a scenario where a system should notify a user if the storage space goes below 5% or above 95%. Which of the following combinations of operators will be suitable for the condition?
- if storage < 5 or storage > 95:
- if storage <= 5 or storage >= 95:
- if storage > 5 and storage < 95:
- if 5 <= storage <= 95:
To check if the storage space goes below 5% or above 95%, you should use the condition if storage <= 5 or storage >= 95:. This condition covers both cases, ensuring that the system notifies the user when the storage falls below 5% or exceeds 95%. The other options do not provide the correct combination of operators for this scenario.
Which Python method is executed when the context of a with statement is entered?
- __enter__()
- __exit__()
- __init__()
- __open__()
The __enter__() method is executed when the context of a 'with' statement is entered. It typically sets up the required resources or context for the code block within the 'with' statement.
Packages in Python provide a way of organizing related modules into a single _______ directory hierarchy.
- File System
- Folder
- Namespace
- Package
Packages in Python help organize related modules into a single folder hierarchy, making it easier to manage and access them in a structured way.
How can you implement a switch-case like behavior in Python?
- By importing the 'switch' module
- By using if-elif-else statements
- By using the 'switch' keyword
- Python does not support switch-case
Python does not have a built-in 'switch' statement, but you can achieve similar behavior using if-elif-else statements to evaluate multiple conditions.
