QUESTION
I've been trying to solve this question from The Coder's Apprentice by Pieter Spronck http://www.spronck.net/pythonbook/pythonbook.pdf, page 146 via pdf, or 132 in the book itself. Here is the exact question:
Write code that uses two strings. For each character in the first string that has exactly the same character at the same index in the second string, you print the character and the index. Watch out that you do not get an “index out of bounds” runtime error. Test it with the strings "The Holy Grail" and "Life of Brian".
I'm aware there is the option to use coord but it's not been covered in the book so far and I want to learn in the precise manner in which the books presents the tools available so that I can really get on top of the fundamentals.
I can find the matching the characters and their corresponding indexes, but I'm at a loss as to how I return only the characters and indexes that exactly match. I've tried quite a few different ideas but I just can't seem to crack it. I've only presented the code that returned the matching characters and their index, not any of the things I tried since they just returned errors
Thanks:

QUESTION
I am sorry for this question. I am working on a option to generated a table using div tags, this works fine. I am trying to make the user add or remove a row using jQuery. My problem is that the added row is not populating all the columns. The entire row is added in the columns Header1. I have tried everything to get this to be fixed but nothing works, you guys are my last hope that is why i posted my question here.
I have tried to make a workable snipchat, the add new row is not working here, it is in my browser..
...ANSWER
Answered 2020-Dec-21 at 13:41- If you are adding long HTML strings, use backticks (`) for interpolation - this allows you to create multi-line strings
- I suggest that you put (especially long) HTML strings outside of your click handler. Much cleaner, easier to track
- You appended the whole HTML string to
#next
instead of your table body containerdivTableBody
- Also, there are one fewer columns than cells you create
- Added
.parent()
to yourremove
function - now it works

QUESTION
I'm working on a problem from the Kotlin Apprentice book in the Lambdas chapter. Here is the problem:
Using the same nameList list, first filter the list to contain only names which have more than four characters in them, and then create the same concatenation of names as in the above exercise. (Hint: you can chain these operations together.)
How can I chain the two lambdas together? Below is my code with separate lines for the 2 lambdas.
...ANSWER
Answered 2020-Nov-16 at 08:09 fun main() {
val nameList = listOf("John", "Jacob", "Jingleheimer", "Schmidt")
val myNameToo = nameList.filter {it.length > 4}.fold("") {a, b -> a + b}
println(myNameToo)
}
QUESTION
Afternoon folks
Following on from a previous question,
I have created a small python app that will scrape job postings for me from a website.
I have them saved in a small sql db
Columns are Job_id / job_title / job company / job_salary / job_location / job_post_date
I was planning on running my script once per day and hoping to ignore duplicate entries.
What sort of query can check against 2 columns I. E. Title and company to make sure it doesn't get inserted again, the date posted will always increment by 1 per day
Python Code
...ANSWER
Answered 2020-Nov-13 at 15:52You would typically put a unique constraint on that tuple of columns, and use update ... on duplicate key
when inserting so duplicates are not inserted, but instead the date of the current row is updatedd.
So something like:

Answered 2020-Oct-05 at 12:22The form is not valid. If it was valid it would save the object. But even if form.save()
would not have the expected side effects, the redirect(…)

You can print the form errors with:
