通过readlines（）方法读取行时发生错误

Question

The following function is defined to read the content of the .csv file and store it into lists:

def _read_txt_file(self):
    self.img_paths = []
    self.labels = []
    with open(self.txt_file, 'r') as f:
        lines = f.readlines()
        for line in lines:
            items = line.split(',')  # .csv
            self.img_paths.append(items[0])
            self.labels.append(int(items[1]))

Something wrong has happened in line 6. The PyCharm debugger shows normal values of variable lines , ie '../ZP_45151/0.bin,0\\n' , '../ZP_45151/0.bin,1\\n' and so forth. But the line variable displays a weird value, that is, ',\\n' , which is obviously that something has been lost. Does anyone have an idea that why the operation is not going through the complete content?

Answer 1

Well, I checked my reading .csv file and found that there are plenty of blank lines expressed as ',\\n' in string format. The issue has been settled.
