How to add a number to each element in list a that gives a new list b with sum added number
Hi How to add a number to each integer in the list A that generates new list B using python. also I want to generate n number of lists Example: a = [1,2,3] and n = 2 add k = 3 to each element in a that gives b = [4,5,6] and add k to list b that gives c = [7,8,9] I achieved this using map function but I want to generate n number of lists.
def bw(n, k): test_list = [1,2,3] if n > 1: res = list(map(lambda x :x+k, test_list)) return test_list, res else: return test_list print bw(3, 2)
Output b = [4,5,6] c = [7,8,9]
If you just want the final array:
def bw(n, k): test_list = [1,2,3] return [x+n*k for x in test_list] print(bw(3, 2))
If you want a list of lists as well:
def bw(n, k): test_list = [1,2,3] res =  for i in range(0,n): test_list = [x+k for x in test_list] res.append(test_list) return test_list, res print(bw(3, 2))
Python, Python | Adding two list elements. There can be many situations in which one requires to find index wise summation of two different lists. This can have a� Given a list of numbers, write a Python program to find the sum of all the elements in the list. Example: Input: [12, 15, 3, 10] Output: 40 Input: [17, 5, 3, 5] Output: 33
res = [x + k for x in test_list]
This is straight from GeeksforGeeks.
Python program to find sum of elements in list, Given a list of numbers, write a Python program to find the sum of all the list. # and add them in variale total print ( "Sum of all elements in given list: " , total)� Contents. 1 Python program to find sum of elements in a list.. 1.1 Find total using sum function. 1.1.1 find the total of integer numbers using the sum() function ; 1.1.2 find the total of decimal numbers using the sum() function
Here is a solution:
test_list = [1,2,3] def bw(test_list, n, k): output=  temp = test_list for i in range(n): temp = [j + k for j in temp] output.append(temp) return output print (bw(test_list, 2, 3))
5.3. Calculating the Sum of a List of Numbers — Problem Solving , An iterative function that computes the sum is shown in ActiveCode 1. To redefine the problem from adding a list to adding pairs of numbers, we could We might say the the sum of the list numList is the sum of the first element of the list� Sum (LINQ) Enumerable.Sum is extension method from System.Linq namespace. It returns sum of numeric values in collection. Sum for Numeric Types. Gets sum of values from list of integer numbers.
Python lists - working with lists in Python, insert() method places an element at a specific position indicated by the index number. The "PHP" string is inserted at the first position, the "Lua"� Minimum number of operations to convert array A to array B by adding an integer into a subarray Find all triplets with zero sum Given an array of distinct elements.
Loops and lists, In general, a list may contain a sequence of arbitrary objects in a given order. To create a list with the numbers from the first column in our table, we just put all the Every element in a list is associated with an index, which reflects the position of the What adding two lists means is up to the list object to define, and not� Create a map to store frequency of each number in the array. (Single traversal is required) In the next traversal, for every element check if it can be combined with any other element (other than itself!) to give the desired sum. Increment the counter accordingly.
List in Python : lists, range, slice, append, len, etc in Python, len() is an useful function which we use on a list. It gives us the length (number of elements) of a list. Python 2; Python 3. Multiply every part of a list by three and assign it to a new list. list1 = [3,4,5] multiplied = [item*3 for item in list1] print multiplied [9,12,15] Note how the item*3 multiplies each piece by 3.
