Question

我正在尝试将一些数据写入txt文件。但是每次它将数据写入两次，而我只希望一次。无法弄清楚..

数据是从计算机收集的，它是cpu，gpu，硬盘驱动器等。我正在收集。

任何帮助都可以申请:)

下面我附上了我使用的模块以及如何在两个列表中收集数据，并将两个列表写入同一文件。

我试图在一个列表中完成所有操作，但是后来我无法收集两个GPU。使用GPU是唯一使用循环收集数据的地方。

import platform                         #   OTHER INFORMATION
from psutil import virtual_memory       #   RAM
import cpuinfo                          #   CPU
from gpuinfo.windows import get_gpus    #   GPU
import psutil                           #   HD

# ----------------------------------------------------------------------------------------------------------------------
content_list = [a, b, c, d, e, g, h, i, j, k, l, m, n]


with open(dataFile, "a") as f:
    for item in content_list:
        f.write("%s\n" % item)


for gpu in get_gpus():
    f = (str("Graphic Card informaion = ") + str(gpu.__dict__))


    gpucontent_list = [f]


    with open(dataFile, "a") as f: 
        for item in gpucontent_list:
            f.write("%s\n" % item)

dataFile的输出看起来像这样，其中所有内容都出现两次。

Answer 1

以“ a”模式打开文件时：

with open(dataFile, "a") as f:

您将以追加模式打开文件，这意味着所有新写入都将写入文件的末尾，而不是替换文件的内容。

您希望以“ w”模式打开文件，这将截断现有内容，并在程序的其余部分保持打开同一文件对象，或者仅对以后的重新打开使用附加模式。

with open(dataFile, "w") as f:
    for item in content_list:
        f.write("%s\n" % item)

    for gpu in get_gpus():
        for item in gpucontent_list:
            f.write("%s\n" % item)
