Question

我想做的是在将数据写入新CSV文件时删除引号。

我尝试使用s.splits和.replaces却没有运气。你们能指出我正确的方向吗？

当前代码：

def createParam():
    with open('testcsv.csv', 'r') as f:
        reader = csv.reader(f)
        csvList = list(reader)

    for item in csvList:
        os.mkdir(r"C:\Users\jefhill\Desktop\Test Path\\" + item[0])
        with open(r"C:\Users\jefhill\Desktop\Test Path\\" + item[0] + r"\prm.263", "w+") as f:
            csv.writer(f).writerow(item[1:])
        f.close

testcsv.csv中的数据：

0116,"139,data1"
0123,"139,data2"
0130,"35,data678"

运行脚本时的数据输出（在每个文件中）：

"139,data1"
"139,data2"
"35,data678"

我想要的数据：

139,data1
139,data2
35,data678

您可以使用str.replace将“（双引号）替换为”（空）。然后split并打印列表中除第一项外的所有内容。

with open('outputfile.csv', w) as outfile:       # open the result file to be written
    with open('testcsv.csv', 'r') as infile:     # open the input file
        for line in infile:                      # iterate through each line in input file
            newline = line.replace('"', '')      # replace double quotes with no space
            outfile.write(newline.split(',',maxsplit=1)[1])  # write second element to output file after splitting the newline once

使用f.close()时不需要with open...
