Type of variables

  They are 

1. 1 Numeric Types:

   • int: Integer values, e.g., 10, -3, 0.
   • float: Floating-point values with decimal points, e.g., 3.14, -2.5, 0.0.
   • complex: Complex numbers with real and imaginary parts, e.g., 2 + 3j, -1j.
   • # Numeric Types

     integer_var = 10

     float_var = 3.14

     complex_var = 2 + 3j

     
     

     print(integer_var) # output 10

     print(float_var)   #output 3.14

     print(complex_var) #output (2+3j)

3. 2 Text Type:

4. • str: String values enclosed in single quotes ('') or double quotes (""). For example, "Hello, World!".
   • 
     

     # Text Type

     string_var = "Hello, World!"

     print(string_var)   #output Hello, World!

1. 3 Sequence Types:

   • list: Ordered and mutable sequences of elements, enclosed in square brackets ([]). For example, [1, 2, 3].
   • tuple: Ordered and immutable sequences of elements, enclosed in parentheses (()). For example, (1, 2, 3).
   • # Sequence Types

     list_var = [1, 2, 3]

     tuple_var = (4, 5, 6)

     print(list_var)     #output [1, 2, 3]

     print(tuple_var)    #output  (4, 5, 6)
   • 
     

2. 4 Mapping Type:

   • dict: Unordered key-value pairs, enclosed in curly braces ({}). For example, {"name": "John", "age": 25}.
   • 
     

     # Mapping Type

     dictionary_var = {"name": "John", "age": 25}

     print(dictionary_var) #output {'name': 'John', 'age': 25}

3. 
   

4. 5 Set Types:

   • set: Unordered collections of unique elements, enclosed in curly braces ({}). For example, {1, 2, 3}.
   • frozenset: Immutable sets, enclosed in curly braces ({}). For example, frozenset({1, 2, 3}).
   • 
     

     # Set Types

     set_var = {1, 2, 3}

     frozenset_var = frozenset({4, 5, 6})

     print(frozenset_var) #output frozenset({4, 5, 6})

5. 
   

6. 6 Boolean Type:

   • bool: Represents either True or False.
   • 
     

     # Boolean Type

     bool_var = True

     print(bool_var)    #output True

7. 
   

8. 7 None Type:

• None: Represents the absence of a value or null.
• 
  

  # None Type

  none_var = None

  print(none_var)    #output None

Here's an example code snippet that demonstrates the different types of variables in Python:

# Numeric Types

integer_var = 10

float_var = 3.14

complex_var = 2 + 3j

# Text Type

string_var = "Hello, World!"

# Sequence Types

list_var = [1, 2, 3]

tuple_var = (4, 5, 6)

# Mapping Type

dictionary_var = {"name": "John", "age": 25}

# Set Types

set_var = {1, 2, 3}

frozenset_var = frozenset({4, 5, 6})

# Boolean Type

bool_var = True

# None Type

none_var = None

# Printing the variables

print(integer_var)

print(float_var)

print(complex_var)

print(string_var)

print(list_var)

print(tuple_var)

print(dictionary_var)

print(set_var)

print(frozenset_var)

print(bool_var)

print(none_var)

OUTPUT :

When you run this code, it will output the values of the variables:

10

3.14

(2+3j)

Hello, World!

[1, 2, 3]

(4, 5, 6)

{'name': 'John', 'age': 25}

{1, 2, 3}

frozenset({4, 5, 6})

True

None
