In this code, how can I check multiple strings in a single string in single statement?
line = '{ AutoLogin = 0; Captive = 0; Closed = 0; Disabled = 0; LastConnected = "2013-11-27 08:38:10 +0000"; Passpoint = 0; PossiblyHiddenNetwork = 0; SPRoaming = 0; SSID = <534253>; SSIDString = SBS; SecurityType = "WPA/WPA2 Personal"; SystemMode = 1; TemporarilyDisabled = 0; })'
for token in line.split( ';' ):
if 'RecentNetworks' in token:
start = True
if 'LastConnected' in token:
start = True
Try this:
for token in line.split(';'):
start = any(s in token for s in ["RecentNetworks", "LastConnected"])
You can use regular expressions for this:
if re.search(r'RecentNetworks|LastConnected', token):
start = True
I'm not sure if this is faster than the any solution, but I assume it.

I'm trying to put text into a RichTextCtrl and then, after the user has made edits, I want to get the edited text back out along with the styles. Its the second part I'm having trouble with. Out of all the methods to get styles out of the buffer, none of them are really user-friendly.
The best I've come up with is to walk through the text a character at a time with GetStyleForRange(range, style). There has got to be a better way to do this! Here's my code now, which walks through gathering a list of text segments and styles.
Please give me a better way to do this. I have to be missing something.
buffer: wx.richtext.RichTextBuffer = self.rtc.GetBuffer()
end = len(buffer.GetText())
# Variables for text/style reading loop
ch: str
curStyle: str
i: int = 0
style = wx.richtext.RichTextAttr()
text: List[str] = []
textItems: List[Tuple[str, str]] = []
# Read the style of the first character
self.rtc.GetStyleForRange(wx.richtext.RichTextRange(i, i + 1), style)
curStyle = self.describeStyle(style)
# Loop until we hit the end. Use a while loop so we can control the index increment.
while i < end + 1:
# Read the current character and its style as `ch` and `newStyle`
ch = buffer.GetTextForRange(wx.richtext.RichTextRange(i, i))
self.rtc.GetStyleForRange(wx.richtext.RichTextRange(i, i + 1), style)
newStyle = self.describeStyle(style)
# If the style has changed, we flush the collected text and start new collection
if text and newStyle != curStyle and ch != '\n':
newText = "".join(text)
textItems.append((newText, curStyle))
text = []
self.rtc.GetStyleForRange(wx.richtext.RichTextRange(i + 1, i + 2), style)
curStyle = self.describeStyle(style)
# Otherwise, collect the character and continue
else:
i += 1
text.append(ch)
# Capture the last text being collected
newText = "".join(text)
textItems.append((newText, newStyle))
Here's a C++ version of the solution I mentioned in the comment above. It's a simple tree walk using a queue, so I think should be translatable to python easily.
const wxRichTextBuffer& buffer = m_richText1->GetBuffer();
std::deque<const wxRichTextObject*> objects;
objects.push_front(&buffer);
while ( !objects.empty() )
{
const wxRichTextObject* curObject = objects.front();
objects.pop_front();
if ( !curObject->IsComposite() )
{
wxRichTextRange range = curObject->GetRange();
const wxRichTextAttr& attr = curObject->GetAttributes();
// Do something with range and attr here.
}
else
{
// This is a composite object. Add its children to the queue.
// The children are added in reverse order to do a depth first walk.
const wxRichTextCompositeObject* curComposite =
static_cast<const wxRichTextCompositeObject*>(curObject);
size_t childCount = curComposite->GetChildCount() ;
for ( int i = childCount - 1 ; i >= 0 ; --i )
{
objects.push_front(curComposite->GetChild(i));
}
}
}
My NodeJS & Python scripts don't return the same hash, what could cause this issue?
Node.js
const { createHmac } = require("crypto");
var message = 'v1:1583197109:'
var key = 'Asjei8578FHasdjF85Hfjkasi875AsjdiAas_CwueKL='
const digest = Buffer.from(key, "base64");
const hash = createHmac("sha256", digest)
.update(message)
.digest("hex");
console.log(hash)
> 7655b4f816dc7725fb4507a20f2b97823979ea00b121c84b76924fea167dcaf7
Python3
message = 'v1:1583197109:'
key = 'Asjei8578FHasdjF85Hfjkasi875AsjdiAas_CwueKL=' + '=' #add a "=" to avoid incorrect padding
digest = base64.b64decode(key.encode('utf-8'))
hash_ = hmac.new(digest, message.encode('utf-8'), hashlib.sha256)
hash_result = hash_.hexdigest()
print(hash_result)
> c762b612d7c56d3f9c95052181969b42c604c2d41b7ce5fc7f5a06457e312d5b
I guess it could be the extra = to avoid the incorrect padding but my key ends with a single =.
Node.js Buffer.from(..., 'base64') can consume the input in the "urlsafe" base64 (https://nodejs.org/api/buffer.html#buffer_buffers_and_character_encodings), and _ is not a valid Base64 character for python, while it is for node.
Adding altchars that correspond to the "urlsafe" version of Base64 to python code yields equal hashes.
const { createHmac } = require("crypto");
var message = 'v1:1583197109:'
var key = 'Asjei8578FHasdjF85Hfjkasi875AsjdiAas_CwueKL='
const digest = Buffer.from(key, "base64");
const hash = createHmac("sha256", digest)
.update(message)
.digest("hex");
console.log(hash) // 7655b4f816dc7725fb4507a20f2b97823979ea00b121c84b76924fea167dcaf7
message = 'v1:1583197109:'
key = 'Asjei8578FHasdjF85Hfjkasi875AsjdiAas_CwueKL=' + '=' #add a "=" to avoid incorrect padding
digest = base64.b64decode(key.encode('utf-8'), altchars='-_')
hash_ = hmac.new(digest, message.encode('utf-8'), hashlib.sha256)
hash_result = hash_.hexdigest()
print(hash_result) # 7655b4f816dc7725fb4507a20f2b97823979ea00b121c84b76924fea167dcaf7
Also, python's b64decode has validate kwarg, which would check the input string and "fail loud" instead of ignoring incorrect characters
I collect the message according to my protofile (listed below). Then I serialize it into a byte string using SerializeToString() method. Then i get the byte string message and deserialization into proto object using ParseFromString() method.
But if i fill in the some fields zero values and execute the above algorithm like this:
def test():
fdm = device_pb2.FromDeviceMessage()
fdm.deveui = bytes.fromhex('1122334455667788')
fdm.fcntup = 0
fdm.battery = 3.5999999046325684
fdm.mode = 0
fdm.event = 1
port = fdm.data.add()
port.port = 1 #device_pb2.PortData.Name(0)
port.value = 0
c = fdm.SerializeToString()
return c
def parse_test(data):
print(data)
res = device_pb2.FromDeviceMessage()
res.ParseFromString(data)
return res
print(parse_test(test()))
, then python console will show me:
deveui: "\021\"3DUfw\210"
battery: 3.5999999046325684
event: PERIOD_EVENT
data {
port: VIBR2
}
without fields values are zero.
But i want to see:
deveui: "\021\"3DUfw\210"
fcntup: 0
battery: 3.5999999046325684
mode: BOUNDARY
event: PERIOD_EVENT
data {
port: VIBR2
value: 0
}
Why is it happening, and if it's fixed how can i fix it?
=============Proto_File================
message FromDeviceMessage{
bytes deveui = 1;
uint32 ts = 2;
int32 fcntup = 3;
float battery = 4;
int32 period = 5;
Mode mode = 6;
Event event = 7;
repeated PortData data = 8;
}
message PortData{
DevicePort port = 1;
int32 value = 2;
}
enum Mode{
BOUNDARY = 0;
PERIOD = 1;
BOUNDARY_PERIOD = 2;
}
enum Event{
BOUNDARY_EVENT = 0;
PERIOD_EVENT = 1;
}
enum DevicePort{
VIBR1 = 0;
VIBR2 = 1;
TEMPL2 = 3;
}
So, i think i guessed the reason. In case enum type ( DevicePort, Event, Mode): the default value is the first defined enum value, which must be 0. So i will set up 1 value to see required fields. In other cases: the fields with zero values are not displayed to reduce memory size of package. But if i turn to the required field using this way: res.data[0].value (in def parse_test(data)) it will show me 0, if i set value 0 in field value, for example. And this rule works in all cases.
I am trying to write a file from a sample template file.
I need to replace ONLY $UPPERINTERFACE with interface.
This is the sample template.txt
localparam $UPPERINTERFACE_WDTH = 1;
localparam $UPPERINTERFACE_DPTH = 8;
localparam $UPPERINTERFACE_WTCHD = 2;
This is the code:
from string import Template
intf = "interface"
rdfh = open("template.txt", "r").readlines()
wrfh = open("myfile.txt", "w")
for line in rdfh:
s = Template(line)
s = s.substitute(UPPERINTERFACE=intf.upper())
wrfh.write(s)
rdfh.close()
wrfh.close()
Expected output:
localparam interface_WDTH = 1;
localparam interface_DPTH = 8;
localparam interface_WTCHD = 2;
As it is taking $UPPERINTERFACE_WDTH as a variable to be replaced, I am getting following error:
KeyError: 'UPPERINTERFACE_WDTH'
Is there any way I can replace only $UPPERINTERFACE with interface here?
You can use curly braces {} to narrow down the template key as in following template string:
>>> line = 'localparam ${UPPERINTERFACE}_WDTH = 1;'
>>> Template(line).substitute(UPPERINTERFACE=intf.upper())
'localparam INTERFACE_WDTH = 1;'
The documentation states the following:
${identifier} is equivalent to $identifier. It is required when valid identifier characters follow the placeholder but are not part of the placeholder, such as "${noun}ification".
So I am trying to access the data from here
in Python. As you can see, it uses wmi. I have tried to use wmi in python before but I am having trouble interpreting the data they are giving me. Please be patient with me as I am a noob to how wmi works. It says that the wmi data is stored in root/OpenHardwareMontor and that it uses two different wmi classes(Hardware and Sensor). But all this information is going over my head.
could someone please give me some sample code to read some data from this?
For example, the code to check cpu core 1 frequency.
EDIT: i have sort of got it working. i run this code:
for Temperature in c.sensor():
print Temperature.identifier
print Temperature.value
and i get this:
/hdd/0/load/0
37.6608924866
/intelcpu/0/temperature/1
53.0
/intelcpu/0/temperature/0
42.0
/ram/data/1
2.88324356079
/intelcpu/0/load/2
1.53846144676
/hdd/0/temperature/0
43.0
/intelcpu/0/load/0
2.30768918991
/intelcpu/0/clock/1
1463.29663086
/intelcpu/0/clock/0
133.02696228
/intelcpu/0/clock/2
1463.29663086
/ram/load/0

/ram/data/0
2.79517364502
/intelcpu/0/load/1
3.07692289352
how can i request only the value associated with the identifier /intelcpu/0/temperature/1 ignoring all other values?
The most simple example to use WMI:
c = wmi.WMI()
wql = "Select * From Win32_SerialPort"
for item in c.query(wql):
print item
Output Example:
instance of Win32_SerialPort
{
Availability = 2;
Binary = TRUE;
Caption = "SpectrumAnalyzer1 (COM15)";
ConfigManagerErrorCode = 0;
ConfigManagerUserConfig = FALSE;
CreationClassName = "Win32_SerialPort";
Description = "SpectrumAnalyzer1";
DeviceID = "COM15";
MaxBaudRate = 128000;
MaximumInputBufferSize = 0;
MaximumOutputBufferSize = 0;
Name = "SpectrumAnalyzer1 (COM15)";
OSAutoDiscovered = TRUE;
PNPDeviceID = "USB\\VID_10C4&PID_ED00\\1269376";
PowerManagementCapabilities = {1};
PowerManagementSupported = FALSE;
ProviderType = "RS232 Serial Port";
SettableBaudRate = TRUE;
SettableDataBits = TRUE;
SettableFlowControl = TRUE;
SettableParity = TRUE;
SettableParityCheck = TRUE;
SettableRLSD = TRUE;
SettableStopBits = TRUE;
Status = "OK";
StatusInfo = 3;
Supports16BitMode = FALSE;
SupportsDTRDSR = TRUE;
SupportsElapsedTimeouts = TRUE;
SupportsIntTimeouts = TRUE;
SupportsParityCheck = TRUE;
SupportsRLSD = TRUE;
SupportsRTSCTS = TRUE;
SupportsSpecialCharacters = TRUE;
SupportsXOnXOff = TRUE;
SupportsXOnXOffSet = TRUE;
SystemCreationClassName = "Win32_ComputerSystem";
SystemName = ".......";
};
You can access each item by:
myQuery = c.query(wql)
myQuery.Availability
Output:
2
For more information, try the WMI cookbook.
Edit #1:
Using if statements and in you can do what you want.
for Temperature in c.sensor():
if "/intelcpu/0/temperature/1" in Temperature.identifier:
print Temperature.identifier
print Temperature.value
