# Program to demonstrate class methods
class Employee:
def __init__(self, name, salary):
self.name = name
self.salary = salary
@classmethod
def from_string(cls, data):
name, salary = data.split("-")
return cls(name, float(salary))
e = Employee.from_string("Alice-75000")
print(e.name, e.salary)Output
Alice 75000.0
Understanding Class Methods
The class method 'from_string' constructs Employee objects from a string representation.
Note: To write and run Python programs, you need to set up the local environment on your computer. Refer to the complete article Setting up Python Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your Python programs.
