w=[]
r=0
t=0
q=int(input("How Many Numbers You Wanna Enter: "))
for i in range(q):
    e=input("Enter A Word: ")
    if e.isalpha==True:
        for i in e:
            if i==" ":
                print("Enter A WORD Not A SENTENCE")
                continue
            else:
                w.append(e)
    else:
        print("Use Alphabets Only")
        continue
for i in w:
    r=len(i)
    if t<r:
        t=r
    else:
        continue
for i in w:
    if len(i)==t:
        print("Longest Word Is: ", i)
    else:
        continue

This Code Is For Printing The Longest Word In A List Of Words. Instead Of Using continue, I Wanna Do Something Do Repeat The Iteration, Like When The User Enter A String With Space Or A Digit, The User Is Prompted Again To Enter The Same Value. Using break Will Stop The Whole Program, Which I Definitely Not Wanna Do. What Should I Do? Please Help
