Answer 1

Python code:

#defining three function
def three(string):
    #splitting it into words list
    string=string.split()
    #looping each word
    for i in range(len(string)):
        #checking if its length is 3
        if(len(string[i])==3):
            #replacing it with ***
            string[i]="***"
    #converting it back to string
    return " ".join(string)
#calling three function for a sample value and printing result
print(three("submit only one question per post."))
