我不理解她在代码

Question

import glob
from shutil import copyfile

emotions = ["neutral", "anger", "contempt", "disgust", "fear", "happy", "sadness", "surprise"] #Define emotion order
participants = glob.glob("source_emotion\\*") #Returns a list of all folders with participant numbers

for x in participants:
    part = "%s" %x[-4:] #store current participant number
    for sessions in glob.glob("%s\\*" %x): #Store list of sessions for current participant
        for files in glob.glob("%s\\*" %sessions):
            current_session = files[20:-30]
            file = open(files, 'r')

            emotion = int(float(file.readline())) #emotions are encoded as a float, readline as float, then convert to integer.

            sourcefile_emotion = glob.glob("source_images\\%s\\%s\\*" %(part, current_session))[-1] #get path for last image in sequence, which contains the emotion
            sourcefile_neutral = glob.glob("source_images\\%s\\%s\\*" %(part, current_session))[0] #do same for neutral image

            dest_neut = "sorted_set\\neutral\\%s" %sourcefile_neutral[25:] #Generate path to put neutral image
            for i in range(len(emotion)):
                dest_emot = "sorted_set\\%s\\%s" %(emotions[emotion],
                                               sourcefile_emotion[25:]) #Do same for emotion containing image

            copyfile(sourcefile_neutral, dest_neut) #Copy file
            copyfile(sourcefile_emotion, dest_emot) #Copy file

上面的代码会抛出如下错误：

runfile('K:/Facedata landmarks/data/load_images.py', wdir='K:/Facedata landmarks/data')
Traceback (most recent call last):

  File "<ipython-input-1-0b76baf7ba54>", line 1, in <module>

ValueError: could not convert string to float: '   9.0000000e+00   4.0000000e+00\n'

我正在读取字符串的文件数据，但我将其作为float读取，最后将其转换为int。但是后来python也在抛出错误。任何人都可以帮我解决这个问题吗？我不明白这里出了什么问题以及如何解决。
