Write a fn collateATPFiles(openType, openPoints) that takes the pathname of the two text files collates them and returns the content of the files

I have to raise value error for the following -

• The file openType does not contain at least two entries per line (for lines that do not start with #).
• The file openPoints has a tournament type not defined in openType and vice-versa
• The file openPoints does not contains exactly 4 entries per line, or if the second, third or fourth entries are not numerical values of type int.

This is my code so far-

def collateATPFiles(openType, openPoints):
    f1=open('openType')
    f2=open('openPoints')
    readinfo1=f1.readline()
    readinfo2=f2.readline()
    if f1 not in readinfo1<=2:
        raise ValueError
