Challenge For each word in words, add ‘d’ to the end of the word if the word ends in “e” to make it past tense. Otherwise, add ‘ed’ to make it past tense. Save these past tense words to a list called past_tense.

words = ["adopt", "bake", "beam", "confide", "grill", "plant", "time", "wave", "wish"]
past_tense = []
for i in words:
    if(i[len(i)-1] == 'e'):
        i += 'd'
    else:
        i += 'ed'
    past_tense.append(i)

Hi!. I realized adding little bit of explanation will help new coder's to understand the code better. :)

words = ["adopt", "bake", "beam", "confide", "grill", "plant", "time", "wave", "wish"]

//creating an empty list named "past_tense"
past_tense = []

for i in words:
if i[-1] == "e": // i[-1] indicates the last element of the i's
i = i+ "d"
past_tense.append(i) // The append() method adds an item to the end of the list.
else:
i = i + "ed"
past_tense.append(i)
print(past_tense)

words = ["adopt", "bake", "beam", "confide", "grill", "plant", "time", "wave", "wish"]
past_tense=[]
for i in words:
if i[-1]=="e":
past_tense.append(i+"d")
else:
past_tense.append(i+"ed")
