Homework Answers
What will be the output of the following code:
class Sales:
def __init__(self,id):
self.id = id
id = 100
val = Sales(123)
print(val.id)
Output: 123
Description:
The __init__() method is same as the constructor in java or C++ language. This method will be called automatically when the class is instantiated. Here, we are defining the method with parameter id. Initializing the class Sales with the value 123 returns the output as 123.
