Look into Python’s assignment operators.

perhaps missing the augmented assignment operator +=

word = "hello"
new_word = "_"
for letter in word:
  new_word += letter + "_"
print(new_word)

Similar, but slightly different, to another response using str.join() and string formatting:

>>> word = "hello"
>>> print(f"_{'_'.join(word)}_")
_h_e_l_l_o_
>>>

To avoid leading and trailing join symbols, you can try this:

word = "hello"
joinword = ""

for (idx,letter) in enumerate(word):
   joinword += letter
   if idx < len(word)-1:
      joinword += "_"

print(joinword)

This will print 'h_e_l_l_o'
