Kirat[ad_1] You’re casting the nullable Activity to a non-null Context in a listener that might be called when the Fragment it no longer attached to an Activity, which means the Activity would be null at that point. You should generally avoid casting with as. In this case, it masks what the problem was. At least … Read more
[ad_1] Based on this file https://pastebin.com/Z3vJsD77 you posted above. You can directly access the chargeLimitSOC property from this model like following – let chargeLimitSOC = chargeState.chargeLimitSOC Relevant part in your model is here – open class ChargeState: Codable { open var chargeLimitSOC: Int? enum CodingKeys: String, CodingKey { case chargeLimitSOC = “charge_limit_soc” } } 1 … Read more
[ad_1] The loop for(int i=0; i<5,i++;) is wrong. The condition i<5,i++ means i++ because the left operand of the comma operator i<5 doesn’t have side effect and simply ignored. i++ is evaluated to the value before the increment. In this case the value is 0, so it is considered as false and the loop body … Read more
[ad_1] If you want the values of all axis from the Magnetometer this will do it. (By default the values is in microTesla) public class MagnetActivity extends AppCompatActivity implements SensorEventListener{ private SensorManager sensorManager; sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); @Override public void onSensorChanged(SensorEvent event) { if (event.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD) { int x_value = event.values[0]; int y_value = … Read more
[ad_1] You are not null-terminating the arrays you create. Try this instead: char* dynamicmem(char size) { char* temp = new char[size + 1]; temp[size] = ‘\0’; return temp; } char* regrow(char* ptr, int size, char c) { char *p = dynamicmem(size + 1); for (int i = 0; i < size; i++) { p[i] = … Read more
[ad_1] You should use im = ax.imshow() when you want add something to the existing axis, for example, a colorbar. If you don’t need to add anything to the axis, then it is fine to just use ax.imshow(). See this: https://www.geeksforgeeks.org/matplotlib-axes-axes-imshow-in-python/ Example from the link: c = ax.imshow(z, cmap =’Greens’, vmin = z_min, vmax = … Read more
[ad_1] Try: a = [(‘aa’, ‘bb’, [‘cc’, ‘dd’]), (‘ee’, ‘ff’, [‘gg’, ‘ff’])] def flatten(tup): lst = [] for x in tup: if isinstance(x, list): lst += x else: lst.append(x) return tuple(lst) output = [flatten(t) for t in a] print(output) # [(‘aa’, ‘bb’, ‘cc’, ‘dd’), (‘ee’, ‘ff’, ‘gg’, ‘ff’)] As you pointed out, applying How to … Read more
[ad_1] when unpacking an iterable, the number of variables must match the values input being assigned. it depends on the values you are trying to unpack from the input. for instance, a,b= input() #12 print(a). #1 print(b). #2 You can easily unpack. However if you pass in more values than variable you will get an … Read more
[ad_1] As the comments stated, it’s not entirely clear where your problem is. It would be nice if you included an example for what you want to understand better, anyway, here’s an example: #include <iostream> void foo(int x) { std::cout << x << std::endl; } void foo(int* x) { std::cout << (*x + 1) << … Read more
[ad_1] No, it’s called unpacking (look it up, it’s common in python) It’s shorthand for W_grad = grad_fn(X_train,y_train,W,b)[0] b_grad = grad_fn(X_train,y_train,W,b)[1] It will only work if grad_fn(…) returns an iterable with two elements, otherwise it will fail. [ad_2] solved Two variables with the same value in Python
[ad_1] Be careful cls is typically used for classmethods for example like this: class Person: def __init__(self, name, age): self.name = name self.age = age @classmethod def fromBirthYear(cls, name, birthYear): return cls(name, date.today().year – birthYear) So it is better to not use it for your own class names to avoid confusion. Comming to your question. … Read more
[ad_1] Generally it was answered in comment, however I’ll add references from official kubernetes documentation. env field uses EnvVar array. Based on EnvVar v1 core API group, name and value should be only strings. Please see EnvVar v1 core And here is an official example to see how variables are set: apiVersion: v1 kind: Pod … Read more
[ad_1] The JSON must be inside of single quotes, or else the shell and curl think that it is all different command line arguments to be parsed. curl -o -skd ‘{ “jsonrpc”: “2.0”, “method”: “addAction”, “params”:{“action”:{“id”: “Syslog”,”name”: “Syslog Action”,”isSystem”: false,”type”: “SendSyslogMessage”,”arguments”: [{“key”: “SyslogServerName”,”value”: “10.41.155.233”},{“key”: “SyslogServerUseTcp”,”value”: “0”},{“key”: “SyslogServerUseTls”,”value”: “0”},{“key”: “SyslogServerNoBsdCompat”,”value”: “0”},{“key”: “SyslogServerCaCertChain”,”value”: “”},{“key”: “SyslogServerAllowOffTimeRangeCerts”,”value”: “0”},{“key”: “SyslogServerPort”,”value”: … Read more
[ad_1] For problems like these, try to associate the output with its indices (or in this case, current_row). Also, it seems like it’s better to start from 0 for this one. 0: 1 1: 2 * 3 2: 4 * * * 5 3: 6 * * * * * 7 4: 8 * * … Read more
[ad_1] Did you mean to hoist the input() in front of the loop? mylist = [‘good’, ‘great’, ‘fantastic’, ‘fine’] q = input(‘how are you?’) for word in mylist: if q == ‘Im ‘ + word: print(‘Have a nice day’) break else: print(‘Sorry for that’) Example sessions: how are you?Im good Have a nice day how … Read more
