工人现在有所有工人的清单

您使用旧样式类有什么原因吗？我在这里使用新样式。
class Student:
sports = []
def __init__(self, row):
self.lname, self.fname, self.ID, self.sport = row
self.sports.append(self.sport)
def get(self):
return (self.lname, self.fname, self.ID, self.sport)
reader = csv.reader(open('copy-john.csv'), delimiter=',', quotechar='"')
print "%-14s|%-10s|%-5s|%-11s" % tuple(reader.next()) # read header line from csv
print "-" * 45
students = list(map(Student, reader)) # read all remaining lines
for student in students:
print "%-14s|%-10s|%-5s|%3s" % student.get()
# Printing all sports that are specified by students
for s in set(Student.sports): # class attribute
print s, Student.sports.count(s)
# Printing sports that are not picked
allsports = ['Basketball','Football','Other','Baseball','Handball','Soccer','Volleyball','I do not like sport']
for s in set(allsports) - set(Student.sports):
print s, 0
希望这能给您一些有关python序列功能的想法。;）
女士们，先生们，7（.5）行。
allsports = ['Basketball','Football','Other','Baseball','Handball',
'Soccer','Volleyball','I do not like sport']
sports = []
reader = csv.reader(open('copy-john.csv'))
for row in reader:
if reader.line_num: sports.append(s[3])
print "%-14s|%-10s|%-5s|%-11s" % tuple(s)
for s in allsports: print s, sports.count(s)
