For example, for a string hello, the result should be _h_e_l_l_o_.

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

but i am not getting _h_e_l_l_o_. this. what am i doing wrong ?

thanks

"".join([f"_{i}" for i in "hello"])+"_" '_h_e_l_l_o_'

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'
