Question

我想每次将变量写入文件并换行。我见过的所有修复程序均无效。我知道使用'\ n'并将其添加到变量中，但实际上并没有做任何事情。

file.write(searchString + '\n')

file.write(searchString)
file.write('\n')

file.write('searchString \n')

以上是我尝试添加新行的内容下面是我的actaul代码，我需要将新的行修复程序实现为

import csv

searchString = input("Please enter a string to be searched through: ")

fileList = ["prices.csv", "pricessplit.csv", "securities.csv", "fundamentals.csv"]

file = open(searchString+ ".txt", "a", newline="")
file.write(searchString + '\n')


index = 0
fileType = []
for i in fileList:
    with open(fileList[index], "r") as b:
        file.write(fileList[index] + '\n')
        reader = csv.reader(b, delimiter=",",)
        for row in reader:
            for field in row:
                 if field == searchString:
                     print(row)
                     file.write(str(row))
                     file.write("\n")
    index = index + 1

我希望它在每次输入数据后都在带有新行的文本文件中我正在使用stovks，所以我希望它显示searchString-新行然后是prices.csv
然后在写完每行的所有数据后显示所有库存，但是要换行

预期输出应为：

OKE

prices.csv
['2010-01-04', 'OKE', '44.880002', '45.579999', '44.880002', '45.709999', '1759600.0']
['2010-01-05', 'OKE', '45.500002', '45.18', '44.589999', '45.749998', '3324900.0']

['2010-01-11', 'OKE', '45.68', '46.410001', '45.44', '46.510002', '1793000.0']
['2010-01-12', 'OKE', '46.209999', '45.729998', '45.56', '46.369998', '1631200.0']
['2010-01-13', 'OKE', '45.989998', '45.92', '45.55', '45.989998', '876900.0']

但是我得到的是：

OKEprices.csv['2010-01-04', 'OKE', '44.880002', '45.579999', '44.880002', '45.709999', '1759600.0']

如何每次都用新行在文件中写入变量（看到的答案无效）
