Quick shift cipher using ord and chr

shift.py

#Found an issue where going from negative to positive int removes space so just shift starting positive int then shift back negative the same int.
text = input('what is the text: ')
key = input('What is the shift: ')

for i in text:
  uni = ord(i)
  encode = int(uni) + int(key)
  print(chr(encode), end='')
  #print(i, uni)
