Python接受用户输入并从列表中删除该输入

Question

I have been trying this for a few days now. I have to read in a file containing zoo animals. (ie ['ID', 'Name', 'Species']) Next, have to accept the user's ID choice and delete from the list. This is what I so far. I am stuck and can't proceed further until this section is complete. I appreciate any comments. Also using python 3.

f = open('ZooAnimals.txt', 'r') #read in file
file = [line.split(',') for line in f.readlines()] #turn file into list
c = input("What ID would you like to delete? ") #accept user input
file1 = list(c)#turn user input into a list item
list.pop(file1) #suppose to pop out the value
print(file)

EDIT:

The file contains the following items for example. [['1', 'Whiskers', 'Siberian Tiger\\n'], ['2', 'Babbity', 'Belgian Hare\\n'], ['3', 'Hank', 'Spotted Python\\n'], ['17', 'Larry', 'Lion\\n'], ['10', 'Magilla', 'Eastern Gorilla\\n'], ['1494', 'Jim', 'Grizzy Bear\\n']]

I want to try and delete for example, ID 2, Babbity, Belgian Hare

This is what I can't do with my current code

Answer 1

list.pop accepts an index as an argument. For lists, this can only be an integer. Also, list('abc') != ["abc"] , but rather ["a", "b", "c"] because of str 's iteration protocol (it goes by letter).

with open("ZooAnimals.txt") as zoo_animals_txt:
    # [("123", "cat", "felis catus"), ...]
    animals = [line.split(",") for line in zoo_animals_txt]

user_input = input("What ID would you like to delete? ")

for index, (id_, name, species) in enumerate(animals):
    if id_ == user_input:
        animals.pop(index)
        break

print("The remaining animals are:")
print(*animals, sep="\n")

Then, to update the file with the change:

with open("ZooAnimals.txt", "w") as zoo_animals_txt:
    for animal_stats in animals:
        print(",".join(animal_stats), file=zoo_animals_txt)

Answer 2

list.pop() removes the last element of a list. You probably want file.remove(c) . Also, remove file1 = list(c) . I'm not sure why that's there.
