# Convert integer to float
int_to_float = float(int_value)
# Convert float to integer
float_to_int = int(float_value)
# Convert string to integer
str_to_int = int(str_value)
# Convert boolean to integer
bool_to_int = int(bool_value)

# Print the casted values and their new types
print("Casted values and their new types:")
print("int_to_float:", int_to_float, type(int_to_float))
print("float_to_int:", float_to_int, type(float_to_int))
print("str_to_int:", str_to_int, type(str_to_int))
print("bool_to_int:", bool_to_int, type(bool_to_int))
Output:

Casted values and their new types:
int_to_float: 10.0 <class 'float'>
float_to_int: 15 <class 'int'>
str_to_int: 25 <class 'int'>
bool_to_int: 1 <class 'int'>
The type() function is used to display the data type of a variable or object.

Operations on List

We can perform different types of operations on a list, like accessing elements, adding elements, and removing elements.
Before performing any operation, we need to first create a list.

Creating a List
You can create a list by placing all the elements inside square brackets [], separated by commas.

L=[] # creates an empty list
L=[1, 2, 3, 4, 5] # creates a list with numeric values
fruits = ["kiwi", "pineapple", "cherry", "orange"] # creates a list with string values
mix=["India", 12, 34.5] # creates a list with mixed data types
nested_list[[1, 2, 3], 12, 5, 6] # creates a nested list

A nested list is a type of list that contains another list as its element.

Indexing in Lists

Lists are indexed, which means each element has a unique position. The index starts at 0 for the first element, 1 for the
second, and so on. Negative indexing starts from the right to left with -1 being the last element.

Length = 5
'p' 'r' 'o' 'b' 'e'
positive index 0 1 2 3 4
negative index -5 -4 -3 -2 -1
