writing a bash script to loop over alphabet and insert arguments into string

I am trying to write a bash script to loop over the alphabet and insert the letters as an argument in a string. This is what I've tried:

for i in {A..Z}
do
        screen -d -m bash -c 'python ~/directory/script.py  $i '  //$i is supposed to evaluate to the letter
done

I am missing how to enter the argument in the string.

Try replacing the single quotes around your 'python... line with double quotes.

Bash won't perform any expansion on strings enclosed in single quotes, which is why $i is not being parsed as you want.
