Add value to array python
Python doesn’t have a specific data type to represent arrays. The following can be used to represent arrays in Python: If we are using List as an array, the following methods can be used to add elements to it: Example 1: Adding elements to an array using append() function Output:
Example 2: Adding elements to an array using extend() function my_input = ['Engineering', 'Medical'] input1 = [40, 30, 20, 10] my_input.extend(input1) print(my_input) Output:
Example 3: Adding elements to an array using insert() function my_input = [1, 2, 3, 4, 5] print(f'Current Numbers List {my_input}') number = int(input("Please enter a number to be added:\n")) index = int(input(f'Enter the index between 0 and {len(my_input) - 1} to add the given number:\n')) my_input.insert(index, number) print(f'Updated List {my_input}') Output: 2. Adding to an array using array moduleIf we are using the array module, the following methods can be used to add elements to it:
Example: import array s1 = array.array('i', [1, 2, 3]) s2 = array.array('i', [4, 5, 6]) print(s1) print(s2) s3 = s1 + s2 print(s3) s1.append(4) print(s1) s1.insert(0, 10) print(s1) s1.extend(s2) print(s1) Output: Output Array Module3. Addition of elements to NumPy arrayWe can add elements to a NumPy array using the following methods:
Example: import numpy # insert function arr1_insert = numpy.array([1, 23, 33]) arr2_insert = numpy.insert(arr1_insert, 1, 91) print(arr2_insert) # append function arr1_append = numpy.array([4, 2, 1]) arr2_append = numpy.append (arr1_append, [12, 13, 14]) print(arr2_append) Output:
ConclusionThus, in this article, we have implemented possible ways to add elements to an array. References
Python doesn’t have any specific data type as an array. We can use List that has all the characteristics of an array. Python array module can be used to create an array of integers and floating-point numbers. If you want to do some mathematical operations on an array, you should use the NumPy module. 1.

How do you add value to an array?When you want to add an element to the end of your array, use push(). If you need to add an element to the beginning of your array, try unshift(). And you can add arrays together using concat().
How do I add values to a NumPy array?How to append numpy arrays. numpy. append() is used to append values to the end of an array. ... . Code. In the first code snippet, the axis is not specified, so arr and values are flattened out.. In the following code snippet, values are appended along axis 1.. For more details, refer to the official documentation.. How do you add a number to each element of an array?We can add any integer to each element in an array by using “+” operator.
