Python中txt文件中的空白行 [英] Blank lines in txt files in Python

问题描述

我几乎完成了我的项目，但是仍然存在一个小问题.我想使用Python在txt文件中写入传感器值.一切正常，但有一件事情:在txt文件中，每个值之间都有空白行.真的很烦，因为我无法将值放入电子表格中.看起来像这样:

I almost finished my project, but there is still one little problem. I want to write sensor values in a txt file with Python. All is working fine but one thing : in the txt file, there're blank lines between each value. It's really annoying because I can't put the values in a spreadsheet. It looks like That:

传感器值:

2

4

6.32

1

等...

当我这样想时:

传感器值:1个2个358等等...

Sensor values: 1 2 3 5 8 etc...

这是相关代码的一部分:

Here's the part of the code concerned :

def write_data():
    global file_stream
    now = datetime.now()
    dt_string = now.strftime("%d-%m-%Y %H_%M_%S")
    file_stream = open("data " + dt_string+".txt", "w") # mode write ou append ?
    write_lines()


def write_lines():
    global after_id
    data = arduinoData.read()
    data2 = data.decode("utf-8")
    file_stream.write(data2)
    print(data2)
    if data2 == "F":
          print("Ca a marché")
           stopacq()
           return
    after_id = root.after(10, write_lines)

谢谢

推荐答案

添加换行符

file_stream = open("data " + dt_string+".txt", "w", newline="")
