I am a beginner user of Python without IT background (I am interested in IT developing my knowledge step by step). So far I did simple scripts in Python and I encountered a problem. I was looking on Google, however I didn't find the satisfactory answers which would help me - Therfore, I decided to write here.
I'm struggling to identify duplicates in CSV file. My CSV file contains contacts from the database. Every column corresponds to particular data (name, surname, job title, company, email, contact ID etc.). In this database there are duplicates and I want to read through this database and identify duplicated emails. If script finds the duplicated email, then it writes email address, contact ID to a separate file - creating new file which will consist of duplicates only. Does anyone could help me with this task? I would much appreciate your help.
