使用正则表达式从文本文件中提取的字符串总和

import reimport nptext = open('text_numbers.txt')final = []for line in text:    line = line.strip()    y = re.findall('([0-9]+)',line)    if len(y) > 0:         lineval = sum(map(int, y))         final.append(lineval)         print "line sum = {0}".format(lineval) print "Final sum = {0}".format(np.sum(final))

那是您要找的东西吗？
