# Accessing all elements at given Python list of indexes

We can access the individual elements of a list using the [] brackets and the index number. But when we need to access some of the indices then we cannot apply this method. We need the below approaches to tackle this.

## Using two lists

In this method, along with the original list, we take the indices as another list. Then we use a for loop to iterate through the indices and supply those values to the main list for retrieving the values.

### Example

Live Demo

given_list = ["Mon","Tue","Wed","Thu","Fri"]
index_list = [1,3,4]

# printing the lists
print("Given list : " + str(given_list))
print("List of Indices : " + str(index_list))

# use list comprehension
res = [given_list[n] for n in index_list]

# Get the result
print("Result list : " + str(res))

### Output

Running the above code gives us the following result −

Given list : ['Mon', 'Tue', 'Wed', 'Thu', 'Fri']
List of Indices : [0, 1, 2, 3, 4]
Result list : ['Tue', 'Thu', 'Fri']

## Using map and geritem

Instead of using the for loop above we can also use the map as well as getitem method to get the same result.

### Example

Live Demo

given_list = ["Mon","Tue","Wed","Thu","Fri"]
index_list = [1, 3,4]

# printing the lists
print("Given list : " + str(given_list))
print("List of Indices : " + str(index_list))

# use list comprehension
res = list(map(given_list.__getitem__,index_list))

# Get the result
print("Result list : " + str(res))

### Output

Running the above code gives us the following result −

Given list : ['Mon', 'Tue', 'Wed', 'Thu', 'Fri']
List of Indices : [1, 3, 4]
Result list : ['Tue', 'Thu', 'Fri']
