#in this program, we will have a basic idea of how to code lists in python
#we will start off by creating a list of numbers
list1=[1,2,3,4,5,6,7,8,9,10]
#this list contains numbers from 1 to 10, all of these are integers, and we will print them out
print(list1)
#we will now understand how to access elements in a list
#positive indexing: we will print the first element of list1, the indexing (counting) starts from 0
print(list1[0]) #this will print 1st element of list1 which is 1
#negative indexing: we will print the last element of list1, the indexing (counting) starts from -1 (from the last)
print(list1[-1]) #this will print the last element of list1 which is 10
#we will now understand slicing in lists
#slicing: we will print the first 3 elements of list1
print(list1[0:3]) #this will print the first 3 elements of list1 which are 1,2,3
#we will now understand how to add elements to a list
#we will add an element to list1
list1.append(11) #this will add 11 to the end of list1
print(list1) #this will print the list1
#we will understand how to insert an element at a specific position in a list
#we will insert an element at the 3rd position in list1
list1.insert(2,"[-]") #this will insert 11 at the 3rd position in list1
print(list1) #this will print the list1

#we will now understand how to remove elements from a list
#we will remove the last element from list1
list1.pop(-1) #this will remove the last element from list1
print(list1) #this will print the list1
#we will remove the 3rd element from list1
list1.remove("[-]") 
print(list1) #this will print the list1

#reversing a list
list1.reverse() #this will reverse the list1
print(list1) #this will print the list1
