I have two df to confrontate. my first df is "sum"

I am trying to iterate over a string that has many repeated characters in order to reorganize it into a list with each character replaced with a 3 letter code and its index+1.

So I want to reorganize:

I'd like to join two dataframes with R here the first one

I have a string and a dictionary. I must replace the parts of the string with corresponding values in the dictionary (using the dictionary keys).

given string:`

I wrote a haskell code for translate RNA codon like this:

I have a PDB file that is returned from a receptor/ligand docking prediction. I don't know why the authors of the program named the chains "A" for both receptor and ligand, but I want to change it. This should be a basic thing that I want to do and I am not sure why I cannot find any example on the internet. What I want to do is simple.

1. Match a line, for example "HEADER lig"
2. Then for every line after that replace column $5 with a "B"

Here is example of input file:

So, I'm trying to write a code to do the following things:

1. Add, into a list, multiple lists. (with protein sequences; AKA amino acids)

2. Count how many of each amino acid (str) there are, per sequence (list).

3. Create a dictionary to associate each key (amino acid) to a specific value (molecular weight)

4. Get the total molecular weight (multiplying the number of each amino acid per its associated value)

5. Sum the total value of each protein sequence (list).

The problem is; I can get the sum of each dictionary but I cannot sum the final values of those dictionaries. Do you know any way of solving this problem?

I have two pages with a similar content and both of them use the bootstrap tab feature to display data. These tabs are steps of a wizard so I don't want to have users to navigate away of the current tab by clicking on another. So I have written this small js to check if the tab has the "disabled" class that will prevent going to that tab.

On one page it works fine, on the other it doesn't identify the "disabled" class and so on click on the title the new tab is displayed. I am looking for suggestion on how to create some breakpoints in my js code and understand where it breaks. This because there is obviously something in my code that is not working but I cannot find what. The console log statement inside the if block is never executed.
