Mastering Python Basics

What are the basic data types in Python?

• int, float, str, bool, list, tuple, set, dict

• integer, decimal, text, map

• char, byte, array, object

• string, number, boolean, list

How do you declare a variable in Python?

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

• var variable_name = value

• let variable_name = value

• variable_name : value

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

• To create a loop that iterates over a list.

• To execute code conditionally based on a boolean expression.

• To define a function in Python.

• To import modules into a Python script.

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

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

• 'While' loops are used for iterating over arrays only.

• 'While' loops require a counter variable to function properly.

• 'For' loops can run indefinitely while 'while' loops have a fixed number of iterations.

What is a list in Python and how is it different from a tuple?

• A list can only contain integers, while a tuple can contain any data type.

• Both lists and tuples are mutable and can be changed.

• A list is mutable and can be changed, while a tuple is immutable and cannot be changed.

• A list is immutable and cannot be changed, while a tuple is mutable and can be changed.

How do you handle exceptions in Python?

• Ignore exceptions and continue execution.

• Use if-else statements to handle exceptions.

• Use try-except blocks to handle exceptions.

• Log exceptions without handling them.

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

Describe the use of 'break' and 'continue' in loops.

• 'break' exits the loop, 'continue' skips to the next iteration.

• 'break' skips to the next iteration, 'continue' exits the loop.

• 'break' and 'continue' both exit the loop without any further action.

• 'break' pauses the loop, 'continue' ends the loop.
