ValueError: need more than 1 value to unpack

[thestudent]

So I am trying to write a program to use a cypher to code a textfile. There is a textfile holding the cypher, and the program is supposed to ask the user which file they want encoded. This is my program so far

#program
textfile = input("What is the name of the file that holds a cypher?")
code = {}
for line in textfile:
        (char, shadow_char) = line.split()
        code[char]= shadow_char
infile = input("What is the name of the file that holds a text?")
outfile = input("Choose a name of a file where the encoded text should be printed?")
 
INFILE = open(infile, "r")
OUTFILE = open(outfile, "w")
for line in INFILE:
    for char in sentence:
        if char in code:
            encoded_sentence += code[char]
        else:
            encoded_sentence += char
 
    OUTFILE.write(sentence+ "\n")
    OUTFILE.write(econded_sentence)
 
INFILE.close()
OUTFILE.close()

i keep getting "ValueError: need more than 1 value to unpack"
for line 4, (char, shadow_char) = line.split()

any help?

line.split() will just return one value. Your code is trying to assign two variables to the result, so Python is telling you that it does not love this.

Try myChar=line.split(), and then myChar[0] for char and myChar[1] for shadow_char.
