Mastering Python Programming

What are the basic data types in Python?

• char, list, tuple, dict

• int, float, array, set

• string, number, boolean, object

• int, float, str, bool

How do you create a list in Python?

• You create a list in Python using curly braces, e.g., my_list = {item1, item2, item3}.

• You create a list in Python using square brackets, e.g., my_list = [item1, item2, item3].

• You create a list in Python by using parentheses, e.g., my_list = (item1, item2, item3).

• You create a list in Python with the list() function, e.g., my_list = list(item1, item2, item3).

What is the purpose of the 'if' statement in Python?

• To define a function in Python.

• To execute code conditionally based on a boolean expression.

• To create a loop that iterates over a list.

• To import modules and libraries in Python.

Explain the use of 'for' loops in Python.

• 'for' loops in Python are used to iterate over sequences or iterables, executing a block of code for each element.

• 'for' loops can only iterate over numbers in Python.

• 'for' loops are used to create classes in Python.

• 'for' loops are used to define functions in Python.

What is a function in Python and how is it defined?

• A function is a built-in data type in Python.

• A function in Python is defined using the 'def' keyword, followed by the function name and parentheses.

• A function is defined using the 'function' keyword.

• Functions in Python are created with the 'create' keyword.

How can you import a module in Python?

• You can import a module by typing 'include module_name'

• Import modules using 'load module_name'

• Use the 'import' statement, e.g., 'import module_name'.

• Use the 'require' statement, e.g., 'require(module_name)'

What is the purpose of the 'with' statement in file handling?

• To read the contents of a file line by line without closing it.

• To create a new file if it does not exist during the operation.

• To append data to an existing file without any restrictions.

• To ensure proper management of file resources by automatically closing the file after its block of code is executed.

How do you read a file in Python?

• Use 'with open(filename, 'w') as file: content = file.read()' to read a file in Python.

• Read a file by calling 'file.read(filename)' directly.

• Use 'open(filename) as file: content = file.read()' to read a file in Python.

• Use 'with open(filename, 'r') as file: content = file.read()' to read a file in Python.

What is exception handling in Python?

• Exception handling in Python is a way to define new data types.

• Exception handling in Python allows developers to manage errors and exceptions using 'try' and 'except' blocks.

• Exception handling in Python is used to optimize code performance.

• Exception handling in Python is a method to improve code readability.

How do you raise an exception in Python?

• throw ExceptionType('Error message')

• raise 'Error message'

• raise ExceptionType

• raise ExceptionType('Error message')
