Solution Exercise 28: try if a list or string is empty with python

Exercise 28 

Write a Python program that tests whether a list is empty or not. Same question for a string of characters.

Solution

First method

Try if a list is empty
# define a list L
L = list()

# try if the list L is empty
if L == []:
    print("The list  L is empty")
else:
    print("The list L is not  empty") 
Try if a string is empty
# define a string s
s=""

# try if the string s is empty
if s == "":
    print("The string s  is empty")
else:
    print("The list s is not  empty")  

Second Method 

Try if a list is empty
# define a list L
L = list()

# try if the list L is empty by using the len() function
if len(L) == 0:
    print("The list  L is empty")
else:
    print("The list  L is not  empty")
Try if a string is empty
# define a string s
s=""

# try if the string s is empty by using the len() function
if len(s) == 0:
    print("The string s  is empty")
else:
    print("The list s is not  empty")
