# define a list
my_list = [1, 2, 3, 4]

# access the first element
first = my_list[0]

# access the last element
last = my_list[-1]

# access the second element
second = my_list[1]

# print the elements
print(first) #this print 1
print(last) #this print 4
print(second) #this print 2

#or you can use this
# define a list
my_list = [1, 2, 3, 4, 5]

# get a slice of the list
sublist = my_list[1:3]

# print the slice
print(sublist) #this print only [2,3]

#Negative indexing means start from the end

-1 refers to the last item, -2 refers to the second last item etc.

thislist = ["apple", "banana", "cherry"]

accessing list elements in python

Comment

#In Python, we call the location of an element in a list its index.

###Python lists are zero-indexed. This means that the first element 
in a list has index 0, rather than 1.###

#Below is an example of this 
calls = ["Juan", "Zofia", "Amare", "Ezio", "Ananya"]
 #Where 
  Element	Index
  "Juan"	 0
  "Zofia"	 1
  "Amare"	 2
  "Ezio"	 3
  "Ananya"	 4
  
###so if we want to call out the 3rd element from the list,
our code would look like this###

print(calls[3])

#this will print out the following:
Amare


#THE BELOW INFO IS VERY IMPORTANT TO NOTE 
When accessing elements of a list, you must use an int as the index. 
If you use a float, you will get an error. 
This can be especially tricky when using division. 

For example print(calls[4/2]) will result in an error, 
because 4/2 gets evaluated to the float 2.0.

To solve this problem, you can force the result of your division to be 
an int by using the int() function. 

int() takes a number and cuts off the decimal point. 
For example, int(5.9) and int(5.0) will both become 5. 
Therefore, calls[int(4/2)] will result in the same value as calls[2], 
whereas calls[4/2] will result in an error.
