TypeError: 'type' object 不可下标。 我怎样才能让它从二维数组中删除一个数组？

Question

I have had a look at answers to similar questions but I just can't make this work. I am quite new to python.

def read():

    set = []
    f = open("error set 1.txt", "r")
    replace = f.read()
    f.close()

    f = open("Test1_Votes.txt", "w")
    replaced = replace.replace(",", "")
    f.write(replaced)
    f.close()



    f = open("Test1_Votes.txt", "r")
    for line in f:
        ballot = []


        for ch in line:

            vote = ch

            ballot.append(vote)

        print (ballot)

        set.append(ballot)


    """print(set)"""
    remove()

def remove():
    for i in range (70):
        x = i - 1
        check = set[x]
        if 1 not in check:
            set.remove[x]
    print(set)

The error is line 37, check = set[x] I'm unsure of what is actually causing the error

Answer 1

In the remove function, you have not defined set . So, python thinks it's the built-in object set , which is actually not subscriptable.

Pass your object to the remove function, and, preferably, give it another name.

Answer 2

Your remove function cant "see" your set variable (which is list, avoid using reserved words as variable name), because its not public, its defined only inside read function. Define this variable before read function or send it as input to remove function, and it should be working.

def read():
    set = []
    f = open("error set 1.txt", "r")
    replace = f.read()
    f.close()

    f = open("Test1_Votes.txt", "w")
    replaced = replace.replace(",", "")
    f.write(replaced)
    f.close()

    f = open("Test1_Votes.txt", "r")
    for line in f:
        ballot = []


    for ch in line:
        vote = ch
        ballot.append(vote)

    print (ballot)

    set.append(ballot)


    """print(set)"""
    remove(set)

def remove(set):
    for i in range (70):
        x = i - 1
        check = set[x]
        if 1 not in check:
            set.remove(x)
    print(set)
