Question

What's the problem in this code??

Pig latin
=========
Convert "hai" to "aihay"
Example 2: "love" to "ovelay"
1st letter to last and add "ay" at the end

st=input ()
a=st.split (" ")
for i in a:
if i[0] == i[-1]:
tmp1=i[0]
tmp2=i.replace (tmp1, "")+tmp1*2+"ay"
else:
tmp1=i[0]
tmp2=i.replace (tmp1, "")+tmp1+"ay"
print (tmp2, end=" ")
print ("")
