ValueError while trying to extract data from file

with open(st) as file:

    for line in file:

        line = line.rstrip()

        name, species, homeworld = line.split("\t")

        characters.append(StarWarsCharacter(name, species, homeworld))

I’m trying to extract data, but I just get a value error:

ValueError:
name, species, homeworld = line.split("\t")
ValueError: not enough values to unpack (expected 3, got 1)

>Solution :

First of all, the name of the file should be a string, the it should be "st". Second, the error is clear: it means that the split returns only one token, but you expected 3. Then, the file you are trying to read is not separated by "\t". In fact, trying to reproduce:

script.py:

with open("st") as file:
    for line in file:
        line = line.rstrip()
        ame, species, homeworld = line.split("\t")

Note that i didnt include the last line because I don’t have these structs.

st:

pluto   dog homeworld

Running the command python script.py i don’t have any error, because my file is correctly separated by "\t".
