Python readline空行

Question

我想用python读取串口，用readline打印结果，但是我在所有结果行之间得到空行。你能告诉我怎样才能删除所有空行？

我的代码：

#!/usr/bin/python

import serial
import time
import sys

ser = serial.Serial("/dev/ttyACM0", 9600)

print ser.readline()
print ser.readline()
print ser.readline()
print ser.readline()
print ser.readline()

我从后面尝试了几个答案，但仍然有空行。我的txt文件如下：

T:  59.30%  22.20 8% 11% N 

T:  59.80%  22.20 8% 11% N 

T:  59.80%  22.20 8% 11% N 

T:  59.80%  22.20 8% 11% N 

但我需要像以下文件：

T:  59.30%  22.20 8% 11% N 
T:  59.80%  22.20 8% 11% N 
T:  59.80%  22.20 8% 11% N 
T:  59.80%  22.20 8% 11% N     

编辑：

找到解决问题的方法：

    line = ser.readline().decode('utf-8')[:-2]

现在工作正常。这-2删除/ n就是全部。

Answer 1

或者：

import serial

with serial.Serial("/dev/ttyACM0", 9600) as ser:
    for line in ser:
        print line.rstrip('\n')

或

import serial

with serial.Serial("/dev/ttyACM0", 9600) as ser:
    for line in ser:
        print line,

Answer 2

while True:
    line = ser.readline()
    if not line.strip():
        continue
    do_something_with(line)

Answer 3

根据these tips，这应该做：

import serial

ser = serial.Serial("/dev/ttyACM0", 9600)

while True:
    line = ser.readline()
    if line:
        print(line)

Answer 4

import serial
ser = serial.Serial('COM11', 115200, timeout = 0.01)
print("Starting up")
while True:
    try:
        line = ser.readline().decode('ascii').strip()
        if line:
            print (line)
    except:
        pass
    ser.flush()
