Python Coding challenge - Day 60 | What is the output of the following Python code?

 

The above code creates two lists a and b, each containing a single element with the value 10. When you use the is operator to compare a and b, it checks if they are the same object in memory. In this case, the two lists are not the same object, even though their contents are the same, so a is b will return False`. Here's the code and the result:

a = [10]

b = [10]

print(a is b)  # This will print False

Even though the values in a and b are the same, they are different objects in memory, so the is comparison returns False. If you want to check if the contents of the lists are equal, you should use the == operator:

a = [10]

b = [10]

print(a == b)  # This will print True
