Question

我有.txt个文件，每个文件都包含一个很长的行，程序停在b.append(int(j))行，导致内存错误。我不明白为什么程序出现内存错误，因为文件大小为2.8 MB，RAM大小为28GB。

if __name__=='__main__':
    path=raw_input("enter file path:")
    image_path=raw_input("enter directory where images are to be stored:")
    count = 0
    for f in sorted(os.listdir(path)):
        print(f)
        file = path+'/'+f
        b = []
        a =[]
        ref =[]
        alt = []

        if (f[:-4] == '0'):
            print('cb1')
            ch = open(file,'r')
            for i in ch:
                b += i.split()
            for j in b:
                b.append(int(j))
            count+=1
            print('cb2')

        elif (f[:-4] == '1'):
            po = open(file,'r')
            for i in po:
                a += i.split()
            for j in a:
                a.append(int(j))
            count+=1

        elif (f[:-4] == '3'):
            re = open(file,'r')
            for i in re:
                ref += i.split()
            count+=1

        elif (f[:-4] == '4'):
            al = open(file,'r')
            for i in al:
                alt += i.split()
            count+=1
        if (count == 4):
            break


    cnt = 0
    for f in sorted(os.listdir(path)):
        print(f)
        file = path+'/'+f
        cnt += 1
        if cnt>4:
            process(path+'/'+f, image_path , f)

    ch.close()
    po.close()
    re.close()
    al.close()

我在ubuntu 16.04上使用python 2.7 64bit，内存为28 GB。可以从here

你有：

for j in b:
    b.append(int(j))

您正在迭代它时将项目附加到b。这样你的列表就会无限增长。

你可能想要做一些像b = [int(j) for j in b]这样的事情。

列表附加内存错误
