Withenumerate(), you do not have to keep track of the length of the loop or the iteration count. You can also avoid explicitly accessing the value using the index operator, likefruits[count]. The enumerate function automatically handles all these features. The Syntax of Python enumerate() Bel...
How to Enumerate in Python To demonstrate how to use enumeration in Python, we’ll start with a list of flavors and label it ‘flavors’. After applying the enumeration function, we’ll print the list which will show that each item has been marked with a numeral sequentially. ...
This can be combined with slicing as we saw earlier or with built-in methods like enumerate(). Example 5: Access elements of array by looping. from array import array # import array class from array module # define array of floats a = array('f', [4,3,6,33,2,8,0]) # Normal ...
Solve real-world problems using the modulo operator Override .__mod__() in your own classes to use them with the modulo operator With the knowledge you’ve gained in this tutorial, you can now start using the modulo operator in your own code with great success. Happy Pythoning!Mark...
Use enumerate() You can make use of theenumerate()function to iterate over both the indices and elements of the list simultaneously. This makes sure that you stay within the bounds of the list. Example: my_list = [5,120,18]fori, elementinenumerate(my_list):print(f"Index{i}:{element...
Many operations in Python return iterators. The list constructor is handy for turning lazy iterables into concrete lists: lines_with_numbers = list(enumerate(lines)) Unlike iterators, lists won't disappear after being looped over just once. Note that, in a sense, this is kind of just anoth...
The following example will show how do enumerate an enum . using System; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } public enum Colors { red, blue, green, yellow } private void button1_Click...
Using the enumerate function, you simultaneously loop through the elements and their indices: for i, item in enumerate(test_array): print(str(i + 1) + ": " + str(item)) The enumerate() function returns the count of the current iteration (stored in the i variable) and the value of...
You can also use a negative step in the slicing syntax for Python: Python In [7]: arr_2[:2:-1] Out[7]: array([6, 5, 4]) In this code, you are not specifying the start index of the slice, you are specifying the stop value should be index 2, and the step should be -...
