Single versus double quotes for variables

What if we used double quotes for the string for name , instead of single quotes? What is the output of the Python code below?

name = "Aditya"
score = 98

message = "Hi %s. You achieved a score of %d in the class." % (name, score)

print message

Hi "Aditya". You achieved a score of 98 in the class. SyntaxError: invalid syntax Hi Aditya. You achieved a score of 98 in the class. TypeError: 'str' object is not callable

Double Quotes just makes adding single quotes in the string possible eg: "Hey how are you 'Saloni'." o/p = Hey how are you 'Saloni'. But since we don't add any single quote its printed as is

Double quotes work the same as single quotes in Python, and in JavaScript, HTML, CSS, Java, along with many other languages. Just be careful not to confuse them together like this: 'Hi!"

Python accepts ("") as well as ('') for assigning string values. So, no error is thrown and the program runs as expected.

In a large number of programming languages single and double quotes are interchangeable when using them to give a string, allowing one to be used by enclosing it in the others (or using an escape character)
