使用python给每一行文本加引号

import os
if __name__ == '__main__':
    f=open('/home/maddaff/Documents/TestSpace/generatecode/joints.txt','r')
    f_w=open('/home/maddaff/Documents/TestSpace/generatecode/joints_write.txt','w')
    line=f.readline()
    while line:
        line=line.strip('n')
        f_w.write("""+line+"""+', ')
        line=f.readline()
    f.close()
    f_w.close()
