Python Programs - Conditional Statements
Compare three strings and print the longest - Python Program
Example 1 :
s1 = input("Enter first string: ") s2 = input("Enter second string: ") s3 = input("Enter third string: ") longest = max(s1, s2, s3, key=len) print("Longest string:", longest)
Output
OUTPUT : Longest string: Elephant
Example 2 :
# Define three strings string1 = "apple" string2 = "banana" string3 = "apple" # Compare string1 and string2 for equality print(f"Is '{string1}' equal to '{string2}'? {string1 == string2}") # Compare string1 and string3 for equality print(f"Is '{string1}' equal to '{string3}'? {string1 == string3}") # Compare string1 and string2 for not equal print(f"Is '{string1}' not equal to '{string2}'? {string1 != string2}") # Check lexicographical order print(f"Is '{string1}' less than '{string2}'? {string1 < string2}") print(f"Is '{string2}' greater than '{string3}'? {string2 > string3}") # Case-insensitive comparison (example with lowercasing) string4 = "Apple" print(f"Is '{string1}' (case-insensitive) equal to '{string4}'? {string1.lower() == string4.lower()}")
Output
OUTPUT : Is 'apple' equal to 'banana'? False Is 'apple' equal to 'apple'? True Is 'apple' not equal to 'banana'? True Is 'apple' less than 'banana'? True Is 'banana' greater than 'apple'? True Is 'apple' (case-insensitive) equal to 'Apple'? True
