I want to write sensor values to a text file with Python. All is working fine but one thing; in the text file, there are blank lines between each value. It's really annoying because I can't put the values in a spreadsheet. It looks like this:

Sensor values:246.321etc....

When I want it without the line breaks:

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

Here's the part of the code which writes the data to file:

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

Add the newline attribute

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