Python List Exercise 1

Python program to find unique numbers in a given list.

 L1 = [1, 9, 1, 6, 3, 4, 5, 1, 1, 2, 5, 6, 7, 8, 9, 2] L2 = [] for x in L1: if x not in L2: L2.append(x) print (L2) 

It will produce the following output −

 [1, 9, 6, 3, 4, 5, 2, 7, 8] 

Python List Exercise 2

Python program to find sum of all numbers in a list.

 L1 = [1, 9, 1, 6, 3, 4] ttl = 0 for x in L1: ttl+=x print ("Sum of all numbers Using loop:", ttl) ttl = sum(L1) print ("Sum of all numbers sum() function:", ttl) 

It will produce the following output −

 Sum of all numbers Using loop: 24 Sum of all numbers sum() function: 24 

Python List Exercise 3

Python program to create a list of 5 random integers.

 import random L1 = [] for i in range(5): x = random.randint(0, 100) L1.append(x) print (L1) 

It will produce the following output −

 [77, 3, 20, 91, 85]
