Array – refers to a variable that can be used to store multiple values at a time. For instance, you may have lists for cars, books, fruits, languages among others.
Look at this example here;
fruits = ["mango", "pineapple", "orange"]
-In that case above you know they are only three fruits, but suppose the fruits are like 500 and you want to access a single value then we use array where we keep the values under a single variable fruits. You can refer to any value in an array as follows;
y = fruits[1]
In this section we will discuss how you can add or remove arrays values, modify arrays values and also finding the length of arrays.
- Adding array values -you can easily add a value to an array as follows using append();
fruits.append("Watermelon")
- Removing array values -You can easily remove any value from an array as follows using pop() or just use remove();
case 1(use of pop()
fruits.pop(2)
case 2(use of remove()
fruits.remove("orange")
- Modify the value of an array – you can easily modify any value of an array. For instance, you modify the second value in the array as follows;
fruits[1] = "Avocado"
- Finding length of an array -You can easily find the number of values in an array or what we call the length of an array as follows using len(). Let’s have an example here;
y =len(fruits)
print(y)
