Access List Index in for Loop in Python (2 Examples)
In this article, I’ll demonstrate how to access a list index in a for loop in Python.
The tutorial contains these contents:
Let’s dive right in!
The following data, which is a list of integers, is used as a basis for this Python tutorial.
some_list = [1, 3, 5, 7, 9, 11, 13, 15] # creating sample list
Example 1: Pairing Indices & Elements of Lists Using enumerate() Function
In this example, we will use the enumerate() function, which takes a list as input and returns a list of tuples. Each tuple is an index/element pair, as given below.
enum_list = enumerate(some_list) # enumerating the list for index, elem in enum_list: print(index, elem, sep=': ') # printing the index-element pairs # 0: 1 # 1: 3 # 2: 5 # 3: 7 # 4: 9 # 5: 11 # 6: 13 # 7: 15
Example 2: Pairing Indices & Elements of Lists Using range() Function
Another way of pairing indices and elements of lists is simply using the index number to get the indices and elements, which can be seen below.
for index in range(len(some_list)): print(index, some_list[index], sep=': ') # printing the index-element pairs # 0: 1 # 1: 3 # 2: 5 # 3: 7 # 4: 9 # 5: 11 # 6: 13 # 7: 15
