Question

我正在建立一个程序，该程序从CSV文件中读取数据，通过一连串的比较来运行该数据，然后告诉用户其数据是否通过了这些测试。但是我一直遇到一个问题，它只读取文件的最后一行

这是我的CSV文件：

1,Gregg,1,True,900,1800
2,Scott,2,False,0,200
3,Trish,3,True,900,1800
4,Rob,4,False,0,200
5,Mat,5,True,900,1800
6,Ben,6,False,0,200
7,Mason,7,True,900,1800
8,Ciaran,8,False,0,200
9,Aaron,9,True,900,1800
10,Dylan,10,False,0,200
11,Allistair,1,True,900,1800
12,Owen,2,False,0,200
13,Mateja,3,True,900,1800
14,Tom,4,False,0,200
15,David,5,True,900,1800
16,Aaron,6,False,0,200
17,Bjork,7,True,900,1800
18,Snorri,8,False,0,200
19,James,9,True,900,1800
20,Madison,5,False,0,200

这是我的记录结构（存储在record.py中）：

class User:
    # Create a record structure for the user, which will encompass and ID, name, level, presence indicator, opentime and closetime
    def __init__(self, usrID, name, lvl, present, opentime, closetime):
        self.usrID = usrID
        self.name = name
        self.lvl = int(lvl)
        self.present = bool(present)
        self.opentime = opentime
        self.closetime = closetime

# return a string of text when the User class is called
    def __repr__(self):
        if self.present == True:
            return "User with ID " + self.usrID + ", with name " + self.name + " has level " + str(self.lvl) + " and is present in the building"
        else:
            return "User with ID " + self.usrID + ", with name " + self.name + " has level " + str(self.lvl) + " and isn't present in the building"

这是我的代码：

def readusrs():

    # define f to open testaccounts.csv
    f = open('csv/users.csv')

    # open testaccounts.csv in csvreader mode
    csvFile = csv.reader(f)

    # reset out counter
    i = 0

    # for every row in the csv file, populate our arrays
    for row in csvFile:
        usrs[i].usrID = row[0]
        usrs[i].name = row[1]
        usrs[i].plvl = (row[2])
        usrs[i].present = bool(row[3])
        usrs[i].oentime = row[4]
        usrs[i].closetime = row[5]

        # incrament i
        i = i + 1

    # return all of the account data
    return usrs

usrs = [record.User("", "", 0, True, "", "")] * 20

usrs = readusrs()

我希望程序中的数据像CSV文件中那样出来，但是全部都像这样：

ID为20的用户（名称为Madison）的级别为0，并且存在于建筑物中

CSV阅读器仅读取python3中的最后一行
