CSV 代码不循环

Question

我正在尝试制作一个小型 Python 脚本来加快工作速度，并让一个小型脚本能够正常工作，但它并没有像我想要的那样工作。这是当前代码：

import re
import csv
#import pdb

#pdb.set_trace()

# Variables
newStock = "newStock.csv" #csv file with list of new stock
allActive = "allActive.csv" #csv file with list of all active
skusToCheck= []
totalNewProducts = 0
i = 0

# Program Start - Open first csv
a = open(newStock)
csv_f = csv.reader(a)

# Copy each row into array thingy
for row in csv_f:
        skusToCheck.append(row[0])

# Get length of array
totalNewProducts = len(skusToCheck)

# Open second csv
b = open(allActive)
csv_f = csv.reader(b)

# Open blank csv file to write to
csvWriter = csv.writer(open('writeToMe.csv', 'w'), delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL)

# Check first value in first row,first file against each entry in 2nd row in second file
with open(allActive, 'rt') as b:
        reader = csv.reader(b, delimiter=",")
        for row in reader:
                if skusToCheck[i] == row[1]:
                        print(skusToCheck[i]) # output to screen for debugging
                        print(row) # debugging
                        csvWriter.writerow(row) #write matching row to new file
                        i += 1 # increment where we are in the first file

伪代码是：

1. 打开文件一并将第一列中的所有值存储在skusToCheck中
2. 根据文件 2 中第 2 列中的值检查该值
3. 如果找到匹配项，（一旦我有这个工作，我希望它也寻找部分匹配项）将行复制到文件 3
4. 如果不移动到skusToCheck 中的下一个值并重复

我似乎无法让第 33 - 40 行循环。它将检查第一个值并在第二个文件中找到匹配项，但不会从skusToCheck 移动到下一个值。

您需要遵循 jonrsharpe 第一条评论中的提示，即将您的 while 循环修改为

# Check first value in first row,first file against each entry in 2nd row in second file
with open(allActive, 'rt') as b:
    reader = csv.reader(b, delimiter=",")
    for row in reader:
    if len(row)>1:
        for sku in skusToCheck:
            if sku == row[1]:
                print(sku) # output to screen for debugging
                print(row) # debugging
                csvWriter.writerow(row) #write matching row to new file
                break

这会检查每个 sku 是否与 allActive 中的所有行匹配
