程序仅读取csv文件的第一行

好的,基本上我有2行数据

name    tribe   id  Air Water   Earth   Fire
Pema    Xero    X14C    24  54  34  43
Otaku   Taru    T111F   54  78  65  78

当前,我的代码根据某些条件检查“ id”列中是否有错误,但是我的代码仅读取第一行(Pema的行)并停止。我不知道是什么原因造成的,解决该问题的任何帮助将不胜感激。

import csv
filePath ="data3.csv"


length="Length of Avatar ID is not 5 "
name_tribe= "Invalid first letter"
score_grade="Invalid last letter"
mid_integers="Invalid integers"

def isValidAvatarIDFormat():
    with open(filePath) as csvfile:
        reader = csv.DictReader(csvfile)
        remarks=[] 
        for row in reader:

            if(len(row['id'])!=5):
                remarks.append(length)


            if(row['tribe'][0] != row['id'][0]):
                remarks.append (name_tribe)


            avg_score= 0
            user,tribe,id, *scores= row.values()
            if all(score.isdigit() for score in scores):
                average= sum([int(score) for score in scores])/4
                if (average >=80):
                    avg_score="A"
                elif (average >=70 and average <80):
                    avg_score="B"
                elif (average >=60 and average <70):
                    avg_score="C"
                elif (average >=50 and average <60):
                   avg_score="D"                    
                elif (average >=40 and average <50):
                   avg_score="E"
                else:
                    avg_score="F"
            if(avg_score != row['id'][-1]):
                    remarks.append (score_grade)


            if (row['id'][1].isdigit() and row['id'][2].isdigit() and row['id'][3].isdigit()):
                    continue
            else:
                remarks.append (mid_integers)

            if (len(remarks) == 1):
                print (remarks)
            elif (len(remarks) >1):
                for i in range(0, len(remarks)):
                    print(remarks[i])

            del remarks 
            remarks =[]           


print("{0:<10}{1:^18}{2:^15}".format("Avatar Name  |","Avatar ID |","Comments"))        
isValidAvatarIDFormat()

在关键的if (row['id'][1].isdigit() and row['id'][2].isdigit() and row['id'][3].isdigit()): continue 循环内,它跳过了其中for列的值在选定位置具有数字的行(因为值id发生了这种情况)

T111F-位置1,2和3的符号是数字,这使得循环使用T111F运算符跳过迭代。

您的情况与行位置无关,但与continue列的选定位置中的特定符号有关。

答案 1 :(得分:0)

您的条件之一是删除一行,但所有行都已被读取:

mortiz@florida:~/Documents/projects/python/testo$ python3 test.py 
Avatar Name  |   Avatar ID |       Comments    
OrderedDict([('name', 'Pema'), ('tribe', 'Xero'), ('id', 'X14C'), ('Air', '24'), ('Water', '54'), ('Earth', '34'), ('Fire', '43')])
Length of Avatar ID is not 5 
Invalid last letter
Invalid integers
OrderedDict([('name', 'Otaku'), ('tribe', 'Taru'), ('id', 'T111F'), ('Air', '54'), ('Water', '78'), ('Earth', '65'), ('Fire', '78')])

因为它是CSV格式,所以我将其格式化为:

name,tribe,id,Air,Water,Earth,Fire
Pema,Xero,X14C,24,54,34,43
Otaku,Taru,T111F,54,78,65,78

名称,部落,ID, Pema,Xero,X14 [C] <-这是一个整数。
