How To Use Python List With Examples
Python List: A Python list is a different data types collection.
lost can be used stored list values. The list is created put the comma separately values between square brackets.
Python offers a variety of compound knowledge varieties usually mentioned as sequences.
The list is one among the foremost often used and extremely versatile knowledge varieties employed in Python.

How To Use Mixed List in Python?
int_list=[11,12,13,14,15 16,17,18,19]
float_list=[4.6,2.6,3.7,8.4,6.3]
Str_list=["java","Python","icoderweb","Google"]
Mix_list=[1234,23.54,"list program"]
print(int_list)
print(float_list)
print(Str_list)
print(Mix_list)
*****OUTPUT*****
[11,12,13,14,15,16,17,18,19]
[4.6, 2.6, 3.7, 8.4, 6.3]
['java', 'Python', 'icoderweb', 'Google']

Python List Index: Python can be used the index square brackets[] to access an item in a list. In Python, indexes start at 0. So python a list having 10 elements will have an index from 0 to 9.
Trying to access indexes aside from these can raise Associate in Nursing IndexError.
The index should be Associate in Nursing number. we won't use float or alternative sorts, this may end in TypeError.
Nested lists are accessed using nested indexing.

data_list=["Python","Java","C"]
print("I Like Language:",data_list[0])
print("I Like Language:",data_list[1])
print("I Like Language:",data_list[2])
*****OUTPUT*****

Python Negative indexing List: Python list allows negative indexing for sequences.
An index of -1 refers to the last item, -2 to the second last item in the python negative list.

Python List Slicing: A Python list can be used to access a range of items in a list by using the slicing operator (:).
Slicing can be using access to any elements from the Slicing method.it is the very most important feature of the Python Language.
How To Use Slicing Methods List in Python?
Slice_list1=['I','C','O','D','E','R','W','E','B']
Slice_list2=['P','Y','T','H','O','N']
print("Slicing List First:",Slice_list1[1:4])
print("Slice List Second:",Slice_list2[2:4])
print("Full Slicing List1 Print:",Slice_list1[0:9])
print("Full Slicing List2 Print:",Slice_list2[0:6
*****OUTPUT*****
Slicing List First: ['C', 'O', 'D']
Slice List Second: ['T', 'H']
