Hi, I have this code, and I have a problem in the output

print("This program finds the intersection of two sets")

sequenceOne = input("Please enter the space-separated elements of the first set: ")
sequenceTwo = input("Please enter the space-separated elements of the second set: ")

sequenceOne = sequenceOne.split()
sequenceTwo = sequenceTwo.split()
listOfIntersection = []

for i in sequenceOne:
    for j in sequenceTwo:
        if (i==j):
            sequenceOne.remove(j)
            sequenceTwo.remove(i)
            listOfIntersection.append(i)
            if not sequenceOne or sequenceTwo:
                pass

it should print string or number intersection between the two sequences.

sequence one : 12 k e 34 1.5 12 hi 12 0.2
sequence two:  1.5 hi 12 0.1 54 12 hi hi hi

intersection: {12, 1.5, 12, hi} #only one [hi] since it occurs once in sequence one

but in my code it skips [hi], and i don't know why
and only printing:

{12,1.5,12}
