How do you declare a variable in Python?

• set variable_name to value

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

• variableName.value

• variable_name : value

What is the difference between a list and a tuple?

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

• A list is mutable and defined with [], while a tuple is immutable and defined with ().

• A list is immutable and defined with [], while a tuple is mutable and defined with ().

• A list is defined with {}, while a tuple is defined with []

How do you create a dictionary in Python?

• You can create a dictionary using square brackets, like this: my_dict = ['key1': 'value1', 'key2': 'value2'].

• Dictionaries are created with parentheses, for example: my_dict = ('key1', 'value1', 'key2', 'value2').

• You can only create a dictionary by importing the dict module.

• You can create a dictionary in Python using curly braces, like this: my_dict = {'key1': 'value1', 'key2': 'value2'}.

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

• To define a function in Python.

• To create a loop that iterates over a list.

• The purpose of the 'if' statement in Python is to execute code conditionally based on a boolean expression.

• To declare a variable in Python.

How do you define a function in Python?

• function_name: parameters

• function_name(parameters) =>

• def function_name(parameters):

• function_name{parameters}

What is the syntax for a 'for' loop in Python?

• for variable in (sequence)

• for variable in sequence[]

• for variable in sequence:

• for (variable : sequence)

How do you append an item to a list in Python?

• Insert the item using my_list.insert(item).

• Use the append() method, e.g., my_list.append(item).

• Combine lists with my_list += [item].

• Use the add() method, e.g., my_list.add(item).

Which Statement(s) are NOT correct:

A) List, Dict and String are Mutable

B) Tuple is immutable

c) String & Tuple are Immutable

D) Dict is Immutable.

• A,D

• B only

• B,C,D

• All are NOT correct

How do you check the type of a variable in Python?

• Use the 'checktype()' function.

• Use the 'type()' function.

• Use the 'instanceof' operator.

• Use the 'var_type()' function.
