python - Python意外缩进错误main()

我不知道怎么解决这个问题。我试过重新输入程序。
最后一个主函数出现意外缩进错误。

resident = 81
nonresident = 162


def main():

    # initialize counters and total tuition
    resident_counter = 0
    nonresident_counter = 0
    total_tuition = 0

    print("Name \tCode\tCredits\tTuition")
    print

    try:
        # open the data file
        infile = open('enroll.txt', 'r')

        # read the first value from the file
        student_name = infile.readline()

        # continue reading from file until the end
        while student_name != '':

            # strip the new line character and print the student's name
            student_name = student_name.rstrip('\n')
            print(student_name, end='\t')

            # read the code type, strip the new line, and print it
            code = infile.readline()
            code = code_type.rstrip('\n')
            print(code_type, end='\t')

            # read the number of credits, strip the new line, and print it
            credits = infile.readline()
            credits = int(credits)
            print(format(credits, '3.0f'), end='\t')

            # check the room type and compute the rental amount due
            # increment the appropriate counter
            if code_type == "R" or room_type == "r":
                payment_due = credits * resident
                resident_counter += 1
            elif code_type == "N" or room_type == "n":
                payment_due = credits * nonresident
                nonresident_counter += 1
            elif code_type != "R" or code_type != "r" or code_type != "N" or code_type != "n":
                payment_due = 0

            # accumulate the total room rent
            tuition += payment_due

            # print the appropriate detail line
            if payment_due == 0:
                print('invalid code')
            else:
                print('$', format(tuition, '8,.2f'))

            # get the next studen't name
            student_name = infile.readline()

        # close the input file
        infile.close()

        # print the counters and payment total amount
        print
        print('total number of resident students: ', resident_counter)
        print('total number of nonresident: ', nonresident_counter)
        print
        print('total students: ', end='')
        print('$', format(tuition, ',.2f'))
# execute the main function

main()

最佳答案

您没有与except匹配的try子句。
