Question

7.2.7: Part 1, Replace a Letter

"Write a function named replace_at_index that takes a string and an integer. The function should return a new string that is the same as the old string, EXCEPT with a dash in place of whatever character was at the index indicated by the integer.
Call your function on the word eggplant and the index 3, like this:
replace_at_index("eggplant", 3)
You should then print the value of s, which should display:
egg-lant"

Answer 1

def replace_at_index(txt, ind):

new_txt = ""

for x in range(len(txt)):

if x == ind:

new_txt += "-"

else:

new_txt += txt[x]

return new_txt

print(replace_at_index("eggplant", 3))

I wrote my code in python 3.8. I hope this helps.
