i tried to make a encryption text program but as i put it to work i get value error can someone help me on the problem

so what the program does is bring the text letter and by reference to (a to z) alphabet list shift the letter to a different order
number in the alphabet and so encrypting the text {if you have any tips on how to present my questions better thats well appreciated also }
now here is the code :
and the erorr is :
position = alphabets.index(letter)
^^^^^^^^^^^^^^^^^^^^^^^
ValueError: ' ' is not in list
what does it mean the value is not in the list why should even be in a list isnt the job of position line to make letters once at a time and than in the end add it to the new_letter line as a string part ?

Code: Select all
alphabets = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w',

'x', 'y', 'z']
directin = input("choose the process as 'encrypt' or 'decrept' in the function\n " )
text = input('enter youre text :\n').lower()
shift= int(input('enter the shift amount:\n'))
def encrypt(plain_text,shift_amount):
ciphar_text = ""
for letter in plain_text :
position = alphabets.index(letter)
new_position = position + shift_amount
new_letter = alphabets[new_position]
ciphar_text += new_letter
print(f'youre encoded text is {ciphar_text}')
encrypt(plain_text=text , shift_amount=shift)and the erorr is :
position = alphabets.index(letter)
