python 读取文本文件的行数据,文件.splitlines()的方法

test_txt = '/home/zcm/tensorf/siamfc-tf-master/data/Biker/groundtruth.txt'
def load_label_set(label_dir):
 label_folder = open(label_dir, "r")
 trainlines = label_folder.read().splitlines() #返回每一行的数据
 for line in trainlines:
 line = line.split(" ") #按照空格键分割每一行里面的数据
 box = [float(line[0]), float(line[1]), float(line[2]), float(line[3])]#box读取标签ground_truth
 label_folder.close()

 return train_box
#train_box = load_train_test_set(test_txt)
