PYTHON Challenge

 Problem: Write a python class and a method called getPositions to extract the positions of a given value. If no argument were provided, the default value is 0.

clue:
data = [1, 0, -1, 0, 0, 1, 1, 0, 0, -1] 
item = MyClass(data)0
print(item.getPositions()) 
print(item.getPositions(1)) 
print(item.getPositions(-1))

Expected output:
[1, 3, 4, 7, 8]
 [0, 5, 6] 
[2, 9]

Solution:

data=[1,0,-1,0,0,1,1,0,0,-1]

class Myclass():

    def __init__(self,data):

        self.data=data

    def getPositions(self,pos=0 ):

        return [i for i,e in enumerate(data) if e==pos]

item = Myclass(data)

print(item.getPositions())

print(item.getPositions(1))

print(item.getPositions(-1))
