Hi,

Mechanical Engineering background will help you to have a strong background in Maths and Stats since it is part of your curriculum. Statistics and Maths are part of Data science. To know coding you can enroll yourself in online courses. There are MOOC platforms which will help you to learn data science from experts. Thus you can upgrade yourself. However you have to work hard in order to achieve your goal. If you really work for it the transition is possible. All the best.
