Question

代码给了我一个错误..我在这里做错了什么

public static final String[] PROJECTION ={

                ContactsContract.Data.MIMETYPE,
                ContactsContract.Data.DATA1,
                ContactsContract.Data.DATA2,
                ContactsContract.Data.DATA3,
                ContactsContract.Data.DATA4,
                ContactsContract.Data.DATA5,
                ContactsContract.Data.DATA6,
                ContactsContract.Data.DATA7,
                ContactsContract.Data.DATA8,
                ContactsContract.Data.DATA9,
                ContactsContract.Data.DATA10,
                ContactsContract.Data.DATA11,
                ContactsContract.Data.DATA12,
                ContactsContract.Data.DATA13,
                ContactsContract.Data.DATA14,
                ContactsContract.Data.DATA15
        };

private static final int MIMETYPE_COLUMN=0;
private static final int DATA_COLUMN=1;
private static final int DATATYPE_COLUMN=2;

private static final String SELECTION = ContactsContract.Data.CONTACT_ID + " = ?";

public static ContactWrapper localContact(long contactId){

    Cursor cursor = getContentResolver().query(ContactsContract.Data.CONTENT_URI,PROJECTION, SELECTION, new String[]{String.valueOf(contactId)}, null);

    ContactWrapper wrapper = new ContactWrapper(contact);
    if(cursor==null){
        return wrapper;
    }
    while(cursor.moveToNext()){

        String mime=cursor.getString(MIMETYPE_COLUMN);
        if (mime.equals(ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)) {
            contact.setU8sDisplayName(cursor.getString(DATA_COLUMN));

        } else if (mime.equals(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)) {
            putPhoneNumber(contact, cursor);

        } else if (mime.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)) {
            putEmail(contact, cursor);

        } else if (mime.equals(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE)) {
            putAddress(contact, cursor);

        }else if (mime.equals(ContactsContract.CommonDataKinds.SipAddress.CONTENT_ITEM_TYPE)) {
            contact.setU8sSIPAddress(cursor.getString(DATA_COLUMN));
        }else if (mime.equals(ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE)) {
            wrapper.setImageBinaryString(getContactPhotoBase64(contactId));
        }

    }
    cursor.close();
    return wrapper;
}
private static void putPhoneNumber(ContactWrapper contact,Cursor data){

    switch (data.getInt(DATATYPE_COLUMN)){
        case ContactsContract.CommonDataKinds.Phone.TYPE_HOME:
            contact.setU8sPhoneHome(data.getString(DATA_COLUMN));
            break;
        case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE:
            contact.setU8sPhoneMobile(data.getString(DATA_COLUMN));
            break;
        case ContactsContract.CommonDataKinds.Phone.TYPE_WORK:
            contact.setU8sPhoneBusiness(data.getString(DATA_COLUMN));
            break;

    }

}

试图制作一个总结数字的线程代码。它给出了下面的错误如果名称 =='主要'： freeze_support（） ...

 #!/usr/bin/env python3

from datetime import datetime

MAX_NUM = 10000
NUMPROCS = 1



# THREADING
from multiprocessing import Process, Queue

start_time = datetime.now() 

def sum_range(start,stop,out_q):
i = start
counter = 0
while i < stop:
counter += i
i += 1
out_q.put(counter)

mysums = Queue()
mybounds = [1+i for i in range(0,MAX_NUM+1,int(MAX_NUM/NUMPROCS))]
myprocs = []

for i in range(NUMPROCS):
p = Process(target=sum_range, args=(mybounds[i],mybounds[i+1],mysums))
p.start()
myprocs.append(p)

mytotal = 0
for i in range(NUMPROCS):
mytotal += mysums.get()

for i in range(NUMPROCS):
   myprocs[i].join()
print(mytotal)
end_time =datetime.now()
print('Time taken : {}'. format(end_time-start_time))

使用线程对数字求和
