Use the function called morse_code. It will take 1 parameter, a word. For example: 'apple'.
Using the given morse coe
def morse_code(word):
morse_dict = {
'a': 'dot-dash',
'b': 'dash-dot-dot-dot',
'c': 'dash-dot-dash-dot',
'd': 'dash-dot-dot',
'e': 'dot',
'f': 'dot-dot-dash-dot',
'g': 'dash-dash-dot',
'h': 'dot-dot-dot-dot',
'i': 'dot-dot',
'j': 'dot-dash-dash-dash',
'k': 'dash-dot-dash',
'l': 'dot-dash-dot-dot',
'm': 'dash-dash',
'n': 'dash-dot',
'o': 'dash-dash-dash',
'p': 'dot-dash-dash-dot',
'q': 'dash-dash-dot-dash',
'r': 'dot-dash-dot',
's': 'dot-dot-dot',
't': 'dash',
'u': 'dot-dot-dash',
'v': 'dot-dot-dot-dash',
'w': 'dot-dash-dash',
'y': 'dash-dot-dash-dash',
'z': 'dash-dash-dot-dot'
}
return ['a']['p']['p']['l']['e']
morse_code(apple)
can someone tell me in another simple words what are we suppose to do here, because i didn't get the question from the first place ? thanks

If the input word is ab, the challenge wants you to return a string with the morse code representation of a, followed by a -, followed by the morse code representation of b, which is given to you as 'dash-dot-dot-dot', so the string to return would be 'dot-dash-dash-dot-dot-dot'.
If the input word is abc, the challenge wants you to return the morse code representation of a, followed by a -, followed by the morse code representation of b, followed by a -, followed by the morse code representation of c, which is given to you as 'dash-dot-dash-dot', so the string to return would be 'dot-dash-dash-dot-dot-dot-dash-dot-dash-dot'.

Python Development Techdegree Student 2,989 Pointsthank you so much for you great explanation
i put this code :
for character in morse_dict: character += morse_dict['n'] + "-" character += morse_dict['b']
return character
but always gets :
Bummer: Uh oh, I didn't get the correct value returned. It should have been dash-dot-dash-dot-dot-dot for the word 'tree'. Instead, it was adash-dot-dash-dot-dot-dot.
from where the "a " before the first dash comes from.

Assuming that the line for character in morse_dict: is your only line not indented, you currently have
for character in morse_dict: # loops through each key of the dictionary, starting with character = 'a' since dictionaries are ordered
character += morse_dict['n'] + "-" # character = 'adash-dot-'
character += morse_dict['b'] # character = 'adash-dot-dash-dot-dot-dot'
return character # returns 'adash-dot-dash-dot-dot-dot' and prevents the for loop from looping again
Your code does not currently use the function's input word, so it will return the same string each time.
