Tool to find first stop-codon in a given ORF

Question

[Alexandra]

Hello! I have coordinates of start-codons of interest and I would like to find coordinates of first stop-codons in corresponding ORFs. Are there any existing tools or codes for such purpose?

you could run an ORFfinder on it? (Transdecoder, longestORF, getORF, ... )

but I assume the assignment is to implement an ORF finder in python? Start from the start codon, continue along the DNAsequence, get each codon (3-base), proceed until encounter a stopcodon.
