When posting your question please:
- Ensure this question is about Python..
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
- Read the question carefully
- Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
- If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
- If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.

Assuming that double-negative is a mistake, then the error is telling you that the table does not exist.

You say the table is there; the error message says the table is not there. Guess which statement we're going to believe?
Start by triple-checking which database you're connecting to. Based on the code, it looks like you're connecting to a file-based database in the current working directory, which is usually the same directory as your code. You have almost certainly added the tables to a different copy of that database.

Hi,
I am trying to understand a code in python:
what something similar to mystruct((0x03).to_byte(),'little') means?. trying to convert it to c.
|
|
|
|
|
You need to provide more details of the actual code you are referring to. Where is the definition of mystruct?
|
|
|
|

please send the codes, i can learn from that
|

That's not how this works. The only code you're ever going to get is the code YOU write.
Nobody is going to do your work for you.

What is the difference between "C:\\my folder" and r"C:\my folder" in Python?
Can the "C:\\my folder" be written as r"C:\my folder"?
Thanks.

Unless an ‘r’ or ‘R’ prefix is present, escape sequences in strings are interpreted according to rules similar to those used by Standard C.
...
When an ‘r’ or ‘R’ prefix is present, a character following a backslash is included in the string without change, and all backslashes are left in the string.
Thus "C:\\folder" and r"C:\folder" represent the same string.

Certainly! In Python, the difference between `"C:\\my folder"` and `r"C:\my folder"` lies in how they handle backslashes within strings:
1. **`"C:\\my folder"`:**
- This is a regular Python string where the backslash `\` is an escape character. When you use `\\`, it represents a single backslash in the resulting string.
- For example, `"C:\\my folder"` would be interpreted as `"C:\my folder"` when used in code.
2. **`r"C:\my folder"`:**
- The `r` prefix before the string denotes a raw string in Python. In a raw string, backslashes are treated as literal characters and are not interpreted as escape characters.
- So, `r"C:\my folder"` represents the string exactly as it is, including the backslash, and results in `"C:\my folder"`.
Yes, you can achieve the same result by using a raw string. Both `"C:\\my folder"` and `r"C:\my folder"` represent the same file path, but using a raw string often makes code more readable and avoids potential confusion with escape sequences.

# Gives the name of the game
print ("\t FLAMES")
print ("\n")
# Take input from user
# And Saved them in lowercase
name1 = input("Name of the first person : ").lower()
name2 = input("Name of the second person : ").lower()
print ("\n")
# If there any space in between names
# In this stage removing all the spaces
rename1 = name1.replace(" ", "")
rename2 = name2.replace(" ", "")
# Added those name
name = rename1 + rename2
# In here removing same characters
for x in name:
if name.count(x) != 1:
name = name.replace(x,"")
# Check total number of remaining characters
number = len(name)
# List of FLAMES acronym
result = ["Friends","Love","Affection","Marriage","Enemy","Siblings"]
while number > 1 :
split_result = (number % len(result) -1)
if split_result >= 0 :
right = result[split_result + 1:]
left = result[: split_result]
result = right + left
else:
result = result[: len(result) - 1]
print("Relationship status :", result[0])
#"split_result = (number % len(result) -1) " SHOWS THAT THERE IS ZERODIVITION ERROR HOW TO CORRECT THAT ?

The issue is with the loop at:
while number > 1 :
split_result = (number % len(result) -1)
if split_result >= 0 :
right = result[split_result + 1:]
left = result[: split_result]
result = right + left
else:
result = result[: len(result) - 1]
You never decrement the value of number so the loop will continue forever, or until some exception occurs. But it is not clear what the code inside the loop is supposed to do, so that also may need some reworking.
[edit]
Having looked again at this code I am not sure that the while statement above is correct. Try replacing it with if instead, thus:
if number > 1:

Thank you so much for your help sir .... I understand what mistake was i done. In while loop I typed
" while number > 0: " that was the mistake i done. I changed that comment into " while len(reult) > 1:".
Now its okey sir. Thank you sir ,Thank you so much for your valuble time

I am trying to get the Coral M.2 card working with CPAI. This is on a new clean Windows build, where I followed the guidance referenced from this page Coral TPU really does its work for CP.AI object recognition! - Blue Iris
All seems OK with CPAI itself but I can't get the Coral module loaded - it throws these errors:
21:31:27:Error trying to start ObjectDetection (Coral) (objectdetection_coral_adapter.py)
21:31:27:An error occurred trying to start process 'C:\Program Files\CodeProject\AI\modules\ObjectDetectionCoral\bin\windows\python37\venv\scripts\Python' with working directory 'C:\Program Files\CodeProject\AI\modules\ObjectDetectionCoral'. The system cannot find the file specified.

The folder exists, but is empty. Have I missed a step in installation? What is the best way to fix this, please? Any advice would be much appreciated. Thanks.
