List Exercises

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 notin L2:
  L2.append(x)print(L2)</pre>


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]
