How do you create a function in Python?

• def function_name(parameters): # function body

• function_name(parameters) -> void: # function body

• create function_name(parameters): # function body

• function function_name(parameters) { // function body }

What is the purpose of the 'return' statement in a function?

• The purpose of the 'return' statement is to provide a value from a function to its caller.

• To create a loop within the function.

• To define the function's parameters.

How can you import a module in Python?

• Import modules using 'load module_name'

• You can import a module with 'include module_name'

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

What is the syntax for reading a file in Python?

How do you write data to a file in Python?

• Use open('filename.txt', 'a') to delete the file contents.

• Use file.write('data') without opening the file first.

• Use open('filename.txt', 'w') to open a file and file.write('data') to write data.
