List in Python :
The list data type is one of the most often used data types in Python. The square brackets [ ] easily identify a Python List. Lists are used to store data items, with each item separated by a comma (,). A Python List can include data elements of any data type, including integers and Booleans.
One of the primary reasons that lists are so popular is that they are mutable. Any data item in a List can be replaced by any other data item if it is mutable. This distinguishes Lists from Tuples, which are likewise used to store data elements but are immutable.
Given a list the task is to print the sum of all positive even numbers ,odd numbers and negative numbers in the given list in python.
Examples:
Example1:
Input:
given list =[23, 128, 4, 19, 233, 726, 198, 199, 203, 13]
Output:
The sum of all positive even numbers in thee given list [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] = 1052 The sum of all positive odd numbers in thee given list [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] = 658 The sum of all positive negative numbers in thee given list [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] = 36
Example2:
Input:
given list =[4, 23, 12, 13, 234, 198, 55, 19, 87, 45]
Output:
The sum of all positive even numbers in thee given list [4, 23, 12, 13, 234, 198, 55, 19, 87, 45] = 444 The sum of all positive odd numbers in thee given list [4, 23, 12, 13, 234, 198, 55, 19, 87, 45] = 210 The sum of all positive negative numbers in thee given list [4, 23, 12, 13, 234, 198, 55, 19, 87, 45] = 36
Python Program to Print Sum of Negative Numbers, Positive Even Numbers and Positive Odd numbers in a List
Below are the ways to print the sum of all positive even numbers ,odd numbers and negative numbers in the given list in python.

Method #1:Using append() and Conditional Statements (User Input separated by newline)
Approach:
 Take the user’s input on the number of elements to include in the list.
 Using a for loop, Scan the elements from the user and append them to a list.
 Using a for loop, retrieve the elements from the list one at a time, determine whether they are positive odd, positive even or negative numbers and append them to various lists say posEven, posOdd ,negNum.
 Calculate the sum of posEven, posOdd ,negNum and print them
 Exit of program
Below is the implementation:
# scanning the total number of elements of the given list totalCount = int( input("Enter the total number of elements of the given list = ")) # Taking a empty list given_list = [] # Using for loop to loop totalCount times for i in range(totalCount): eleme = int(input("Enter some random element(integer) = ")) given_list.append(eleme) # Taking three empty lists which stores positive # ven numbers ,positive odd numbers and negative numbers posEven = [] posOdd = [] negNum = [] # Traversing the list using for loop for element in given_list: # checking if the number is greater than 0 if(element > 0): # if the element is even then add this element to posEven using append() function if(element % 2 == 0): posEven.append(element) # if the element is even then add this element to posOdd using append() function else: posOdd.append(element) # else if the number is less than 0 then add to negNum list using append() function else: negNum.append(element) # Calculating sum posEvensum = sum(posEven) posOddsum = sum(posOdd) negNumsum = sum(negNum) # printing the respectve sum's print("The sum of all positive even numbers in thee given list = ", given_list, posEvensum) print("The sum of all positive odd numbers in thee given list = ", given_list, posOddsum) print("The sum of all positive negative numbers in thee given list = ", given_list, negNumsum)
Output:
Enter the total number of elements of the given list = 10 Enter some random element(integer) = 4 Enter some random element(integer) = 23 Enter some random element(integer) = 12 Enter some random element(integer) = 13 Enter some random element(integer) = 234 Enter some random element(integer) = 198 Enter some random element(integer) = 55 Enter some random element(integer) = 19 Enter some random element(integer) = 87 Enter some random element(integer) = 45 The sum of all positive even numbers in thee given list [4, 23, 12, 13, 234, 198, 55, 19, 87, 45] = 444 The sum of all positive odd numbers in thee given list [4, 23, 12, 13, 234, 198, 55, 19, 87, 45] = 210 The sum of all positive negative numbers in thee given list [4, 23, 12, 13, 234, 198, 55, 19, 87, 45] = 36
Method #2:Using append() and Conditional Statements (Static Input separated by spaces)
Approach:
 Given the input of the list as static.
 Using a for loop, retrieve the elements from the list one at a time, determine whether they are positive odd, positive even or negative numbers and append them to various lists say posEven, posOdd ,negNum.
 Calculate the sum of posEven, posOdd ,negNum and print them
 Exit of program
Below is the implementation:
# given list given_list = [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] # Taking three empty lists which stores positive # even numbers ,positive odd numbers and negative numbers posEven = [] posOdd = [] negNum = [] # Traversing the list using for loop for element in given_list: # checking if the number is greater than 0 if(element > 0): # if the element is even then add this element to posEven using append() function if(element % 2 == 0): posEven.append(element) # if the element is even then add this element to posOdd using append() function else: posOdd.append(element) # else if the number is less than 0 then add to negNum list using append() function else: negNum.append(element) # Calculating sum posEvensum = sum(posEven) posOddsum = sum(posOdd) negNumsum = sum(negNum) # printing the respectve sum's print("The sum of all positive even numbers in thee given list ", given_list, "=", posEvensum) print("The sum of all positive odd numbers in thee given list ", given_list, "=", posOddsum) print("The sum of all positive negative numbers in thee given list ", given_list, "=", negNumsum)
Output:
The sum of all positive even numbers in thee given list [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] = 1052 The sum of all positive odd numbers in thee given list [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] = 658 The sum of all positive negative numbers in thee given list [23, 128, 4, 19, 233, 726, 198, 199, 203, 13] = 36
