Educational - Using replace when iterating through list

a2 = 'Hello my name is sofiene'
b2 = ['Hello', 'is']

for item in b2:  # Iterates through words in b2 using 'item' at iterator
    replace_words2 = a2.replace(item, '')  # searches string for each word and replaces it with nothing
    a2 = replace_words2 # Redefines a2 after being modified with replace

print(a2)
