This is the censor dispenser challenge on codecademy!

I’ve been stuck at a particular part for awhile and honestly it’s been a struggle.

Been questioning if i’m an idiot who simply can’t learn.

I need your advice and please please help! I would appreciate them all.

    emailstring = emailstring.replace(emailstring[i], '-')

    emailstring = emailstring.replace(emailstring[i-1], '-')

    emailstring = emailstring.replace(emailstring[i+1], '-')

for word in negative_words:
