methods in python

#Objects can also contain methods. Methods in objects are functions that belong to the object.
#Let us create a method in the Person class:

class Person:
  
  def __init__(self, name, age):
    self.name = name
    self.age = age

  def myfunc(self): # This is a method
    print("Hello my name is " + self.name)

p1 = Person("John", 36)
p1.myfunc()

'vesuvius'.indexOf('u'); //3 - only returns FIRST matching index
'cactus'.indexOf('z'); //-1 not found

// slice - returns a "slice" of a string
"pancake".slice(3); //"cake" - slice from index 3 onwards
