在损坏的 CSV 中加入并添加双引号

Question

我尝试用 python 读取 csv，但我注意到 csv 已损坏并且某些行没有双引号。

Hi everybody (happy new year!).

According to RN2483 datasheet, its best sensitivity performance in LoRa modulation is -146dBm. However, in order to achieve such a sensitivity, the SX1276 transceiver inside the RN2483 module requires a receive bandwidth of 10.4KHz or less.
Unfortunately, the RN2483 API does only support bw configuration of 500, 250 and 125 KHz. Using a bw value of 125KHz the SX1276 transceiver should be capable to perform a maximum sensitivity of -136dBm.

Am I missing something, or is there actually some trouble with RN2483 datasheet (or command interface) ?

这是我尝试读取 csv 的方式：

with open(pathCsv, encoding="utf-16") as f:
    csv_reader = csv.DictReader(f)
    for row in csv_reader :
        print(row.get('commentText'))
        break

当我迭代 csv 时，我得到了以下输出：

print(row.get('commentText'))
>> [p]

我想知道如何再次加入文本并在文本中添加双引号。

这适用于问题中显示的数据。如果要处理的 CSV 文件包含多行，则需要采用不同的方法。

from csv import DictReader

with open(pathCsv) as data:
    columns, *content = map(str.strip, data)
    merged = [columns, ''.join(content)]
    for r in DictReader(merged):
        print(r.get('commentText'))

输出：
