Question

for Power Set can I have it written in python with no hard coded data and it must receive data from the user .

Answer 1

PROGRAM CODE :

import math #importing python math package

#defining Python Function Named findPowerSet with arguments user entered SET and SIZE of the set

def findPowerSet(set,setSize) :

#Setting the size of the Power Set of the set with setSize n is (2**n -1).Empty Set won't be printed

powerSetSize = (int) (math.pow(2, setSize))

#defining counter variable and setting its value equals to 0

counter = 0

#defining a j variable and setting its value equals to 0

j = 0

print("\nPOWER SET : ")

#incrementing the counter value from 0 to the size of the POWER SET

for counter in range(0, powerSetSize) :

#incrementing the j value from 0 to size of the user entered SET

for j in range(0, setSize) :

#Check if jth bit in the counter is set. If set then print jth element from SET

if((counter & (1 << j)) > 0) :

#printing the jth element from the SET

print(set[j], end = "")

#printing the new line

print("")

#prompting the user to set the elements of the SET separated by COMMAS

inputSet = input("\nENTER ELEMENTS OF THE SET SEPARATED BY COMMAS : ")

#splitting the SET ELEMENTS on the basis of the COMMAS and storing it into the SET list

set = inputSet.split(",")

#finding the size of the SET

size = len(set)

#printing the user entered SET after converting it into String

print("\nSET ENTERED: "+str(set))

#calling the function findPowerSet with the SET list and size of the SET list

findPowerSet(set,size)

PROGRAM CODE :

The above program is written in Python Programming Language using Notepad++ and is saved as PowerSet.py

As it is a Python Program, it has to be saved with .py extension

The Python Version used is Python 3.7.0
