如何阅读，验证和移动.csv文件？

There's data like name, age, email etc. So the name should have only letters, age should be numeric and email should be in valid email format. The file which has invalid data in any of the row, there shouldn't be any further processing of that particular csv file and it should be moved to another folder which will have erroneous csv files and the program will move onto next csv in the folder until all of them gets checked, validated and moved.
