import csv
aList=[]
workingdir = r"C:\Users\Akshay.Jain\Desktop\CAREER CONNECT"
csvfile = workingdir+r"\01_Wells.csv"
out = csv.writer(open("myfile.csv","w",newline=''),delimiter=',')

with open(csvfile, 'r') as f:
    reader = csv.reader(f, skipinitialspace=True,delimiter='|', quoting=csv.QUOTE_NONE)
    for row in reader:
        for elements in row:

            elements.strip()
            aList.append(row)

        out.writerow(row)

Answer 1

你的行

 out.writerow(row)

再次写入原始row。尝试像

这样的东西

 out.writerow(aList)

（创建aList移入循环并将elements添加到aList）或直接修改row，正如@mgilson在评论中指出的那样：

for row in reader:
    row = [x.strip() for x in row]
    out.writerow(row)

Answer 2

import csv
aList=[]
workingdir = r"C:\Users\Akshay.Jain\Desktop\CAREER CONNECT"
csvfile = workingdir+r"\01_Wells.csv"
out = csv.writer(open("myfile.csv","w",newline=''),delimiter=',')

with open(csvfile, 'r') as f:
    reader = csv.reader(f, skipinitialspace=True,delimiter='|', quoting=csv.QUOTE_NONE)
    for row in reader:
        for elements in row:

            elements.strip()
            aList.append(elements[:-1])  # Add element by element, removing last item.

        out.writerow(aList[1: -1])  # Write list without first or last item, they are ","

输出：

1497/1,ACERNO-1,1,99000010119101,RUCOPY :Database tree copy,LEGACY_DATA,283,OFDB_IT_SIEP
