Question 49: #python
What is the purpose of the 'setattr' function in Python?
❤️The setattr function in Python is used to dynamically set the value of an attribute on an object.

❤️This function takes three arguments: the object, the attribute name, and the value to be set.

❤️This function is usually used in situations where attribute names or values are determined at runtime.
