This has nothing to do with PyCharm, you are just closing your file before use. This should work

with open ('anscombe.csv', 'r') as datafile: 
    csv_reader = csv.reader(datafile) 
    for line in csv_reader:
        print(line)

with opens the file at the start of the block and closes it at the end by calling the __enter__ and __exit__ methods of file at start and end. For more information read: https://www.python.org/dev/peps/pep-0343/
