It is also possible to delete the entire array by just giving the array name without any index position. ![]() We can remove elements from the array by making use of the del function and specifying the index position for which we would like to delete the array element. ![]() We can also directly access the last element of the array by specifying the index as -1 (minus 1). The index in an array starts at 0, and it increments by 1 as we go through. In the below example, we have created an array of numbers, and then we have printed the very first element of the array by specifying the index position with square braces of num array. We can access elements of the array by specifying the index position. Next, we have changed the array elements from the second position to the fourth position, and then we have printed it. We have replaced the first element of the array with the number 10, and then we have printed the array. Below is an example of how we can do this import array as arrĪs we see, we have first created an array called “num”. Arrays are mutable and the elements of an array can be changed. In this section, we will try to update and change the elements of the array. The final result has the elements from both the arrays. Here, we have defined two different arrays with name cars1 and cars2, and we have then added these two arrays and stored inside an array called the car, then we have simply printed the car array. It is also possible to concatenate to different arrays. In that scenario, we can make use of the extend function.Ĭars.extend()Īs we can see here, we have used extend function to add multiple elements to the array at once, and then we have printed our array. Well, what if we would want to add several elements at a time to the array and not just one? In the third line of the code, we have used the append function to add another car element, “Bugatti”, to the existing array. ![]() Now suppose, if we would like to add more elements to the array, we can make use of the append function. Here, we have defined an array with the name “cars”, and as in the first line of the code, the elements of the array are Ford, Volvo, and BMW. row = int(input("Input the number of rows: "))Ĭol = int(input("Input the number of columns: ")) Method 3 – In this method, we will be asking the users input to know the number of rows and columns we can use the input method for taking the user’s input. Method 2 – Here, we will be defining the size of the array and then will try to do some basic operations and then we will print our array. Method 1 – Here, we are not defining the size of rows and columns and directly assigning an array to some variable A.Ī =, ,, ] Let us see how we can create a 2D array in Python
