Encode string into its original uncoded form

Question

Hi programmers. I‘m relatively new to python and I‘m doing a course in my university to learn it. I have to following problem. I have to encode the following type of strings:
H-VCG EIEOS L--D- LLEI- OONN-
It should be: ‚HELLO I LOVE ENCODINGS‘
I already have the following function:
def decode(input_string):
mylist = [ ]
string = ""
mylist.append(input_string[0])
for i in range(len(input_string)):
if(input_string[i] == ' '):
mylist.append(input_string[i+1])
for i in mylist:
string += i
return string
THIS RETURNS ONLY THE STRING ‚HELLO‘
THE FOLLOWING STRINGS SHOULD ALSO WORK WITH THIS FUNCTION:
assert_equal(decode("H-VCG EIEOS L--D- LLEI- OONN-"), 'HELLO I LOVE ENCODINGS‘)
assert_equal(decode("NHRHA OA-IG BLRSE OLE-- D-AM- YEDE- -V-S- SETS-"), 'NOBODY SHALL EVER READ THIS MESSAGE')
Thank you for any solutions or tips!!
