Basic Python Concepts

What are the main data types in Python?

• boolean, character, array

• string, number, object

• float, string, boolean

• The main data types in Python are: int, float, str, list, tuple, set, dict.

How do you declare a variable in Python?

• You declare a variable in Python by using the syntax: variable_name = value.

• let variable_name = value

• variable_name : value

• var variable_name = value

What is the purpose of an if statement?

• To declare a function in a program.

• The purpose of an if statement is to control the flow of execution in a program based on conditions.

• To create a loop that runs multiple times.

• To define a variable in a program.

Explain the difference between 'while' and 'for' loops.

• The main difference is that 'while' loops are condition-based and can run indefinitely, while 'for' loops are count-based and run a specific number of times.

• 'For' loops can run indefinitely while 'while' loops cannot.

• 'While' loops are always faster than 'for' loops.

• 'While' loops require a specific number of iterations to execute.

What is a function in Python?

• A function in Python is a defined block of code that performs a specific task and can take inputs and return outputs.

• A function in Python is a graphical user interface component.

• A function in Python is a type of variable that stores data.

• A function in Python is a built-in method that cannot be modified.

How do you import a module in Python?

• load module_name

• require module_name

• import module_name

• include module_name

What is the output of the following code: print(type(5))?

Describe the flowchart symbols used in algorithms.

• Square (Condition)

• Circle (Loop)

• Hexagon (Output)

• Flowchart symbols include Oval (Start/End), Rectangle (Process), Diamond (Decision), Parallelogram (Input/Output), and Arrows (Flow).

What is the purpose of the 'break' statement in loops?

• To continue to the next iteration of a loop.

• To exit a loop prematurely.

• To skip the current iteration of a loop.

• To pause the execution of a loop temporarily.

How do you create a list in Python?

• You create a list in Python using square brackets, e.g., my_list = [] or my_list = [1, 2, 3].

• You create a list in Python by calling the list() function, e.g., my_list = list(1, 2, 3).

• You create a list in Python by using parentheses, e.g., my_list = (1, 2, 3).

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