Qus

What will be the output of the following Python code?

>>> a={1,2,3}

>>> b=a.copy()  >>> b.add(4)

>>> a

Qusनिम्नलिखित पायथन कोड का आउटपुट क्या होगा?

A. {1,2,3}
B. Error, invalid syntax for add
C. {1,2,3,4}
D. Error, copying of sets isn’t allowed

A. {1,2,3}

In the above piece of code, b is barely a copy and not an alias of a. Hence any change made in b isn’t reflected in a.
