为什么我在if n％i行的n处收到语法错误？

Question

我第一次尝试使用python 3.7代码：

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
RequestConfig.Builder requestBuilder = RequestConfig.custom().setConnectTimeout(5000).setSocketTimeout(10000);
Registry<AuthSchemeProvider> authSchemeRegistry = RegistryBuilder.<AuthSchemeProvider> create().register(AuthSchemes.NTLM, new NTLMSchemeFactory())
        .register(AuthSchemes.NTLM, new SPNegoSchemeFactory()).build();
CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY, new NTCredentials("MyUsername", "MyPassword", "", "MyDomain"));
HttpClientBuilder builder = HttpClientBuilder.create().setConnectionManager(cm).setDefaultRequestConfig(requestBuilder.build())
        .setDefaultAuthSchemeRegistry(authSchemeRegistry).setDefaultCredentialsProvider(credentialsProvider);
HttpHeaders headers = new HttpHeaders();
HttpEntity<String> entity = new HttpEntity<>("parameters", headers);
RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory(builder.build()));
List<ClientHttpRequestInterceptor> interceptors
        = restTemplate.getInterceptors();
if (CollectionUtils.isEmpty(interceptors)) {
    interceptors = new ArrayList<>();
    restTemplate.setInterceptors(interceptors);
}
restTemplate.getInterceptors().add(clientHttpRequestInterceptor);

正确的代码：

public class HomeWatcher {

    static final String TAG = "hg";
    private Context mContext;
    private IntentFilter mFilter;
    private OnHomePressedListener mListener;
    private InnerRecevier mRecevier;

    public HomeWatcher(Context context) {
        mContext = context;
        mFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
    }

    public void setOnHomePressedListener(OnHomePressedListener listener) {
        mListener = listener;
        mRecevier = new InnerRecevier();
    }

    public void startWatch() {
        if (mRecevier != null) {
            mContext.registerReceiver(mRecevier, mFilter);
        }
    }

    public void stopWatch() {
        if (mRecevier != null) {
            mContext.unregisterReceiver(mRecevier);
        }
    }

    class InnerRecevier extends BroadcastReceiver {
        final String SYSTEM_DIALOG_REASON_KEY = "reason";
        final String SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS = "globalactions";
        final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";
        final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";
        final String SYSTEM_DIALOG_REASON_LONG_PRESS = "assist";
        final String SYSTEM_DIALOG_REASON_VOICE_INTERACTION = "voiceinteraction";

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {
                String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);
                if (reason != null) {
                    Log.e(TAG, "action:" + action + ",reason:" + reason);
                    if (mListener != null) {
                        if (reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {
                            mListener.onHomePressed();
                        } else if (reason.equals(SYSTEM_DIALOG_REASON_RECENT_APPS)) {
                            mListener.onHomeLongPressed();
                        } else if (reason.equals(SYSTEM_DIALOG_REASON_LONG_PRESS)) {
                            mListener.onHomeLongPressed();
                        } else if (reason.equals(SYSTEM_DIALOG_REASON_VOICE_INTERACTION)) {
                            mListener.onHomeLongPressed();
                        }
                    }
                }
            }
        }
    }
