The “Numpy” module provides a function named “np.array()” to create a “1-D” and “2-D” array. The “for” loop iterates over the initialized array and the “print()” function is used to print the elements of the array. Output: The “1-D” and “2-D” arrays have been...
The following example demonstrates how to add to an array using the append(), extend(), and insert() methods: import array # create array objects, of type integer arr1 = array.array('i', [1, 2, 3]) arr2 = array.array('i', [4, 5, 6]) # print the arrays print("arr1 is:...
To calculate the length of an array in Python, you can use afor loop. First, create an array usingarray()function and set the length to'0'. Then, apply for loop over an array and for each iteration,increment the loop by 1and increase the length value. Finally, we can get the lengt...
Converting a Python string to an array involves breaking down a string into individual elements or characters and storing them as an ordered sequence in an array. This is commonly achieved using the split() method, which divides the string based on a specified delimiter, such as a space or c...
Python Dictionary Iteration Dictionaries are one of the most important and useful data structures in Python. Learning how to iterate through a Dictionary can help you solve a wide variety of programming problems in an efficient way. Test your understanding on how you can use them better!Getting...

Python: How to iterate list in reverse order #1 for index, val in enumerate(reversed(list)): print len(list) - index - 1, val #2 def reverse_enum(L): for index in reversed(xrange(len(L))): yield index, L[index] L = ['foo', 'bar', 'bas']...
It’s a simple approach to reverse an array without using some auxiliary space only by interchanging values. Hence, the time complexity of the reverse array isO(n), and its space complexity isO(1). You must iterate only through the first half of an arrayarr.Length / 2. Iterating through...
The most straightforward way to sum an array in JavaScript is by using a classic for loop. This method is particularly useful for beginners to understand how arrays work and how to iterate through them. function sumArray(arr) { let sum = 0; for (let i = 0; i < arr.length; i++) ...
for i in "${array[@]}" do echo "$i" done # Output: # item1 # item2 # item3 In this example, we’ve created an array with three elements: ‘item1’, ‘item2’, and ‘item3’. We then use a ‘for’ loop to iterate through each element in the array. The"${array[@]}"...
