将两个文件内容进行拼接
fid_a = open('a.txt')
fid_b = open('b.txt')
fid_c = open('c.txt','w')
lines_a = fid_a.readlines()
lines_b = fid_b.readlines()
lines_c = []
for i in range(0,len(lines_b)):
lines_a[i]= lines_a[i].strip('\n\r')
lines_c.append(lines_a[i]+lines_b[i])
fid_c.writelines(lines_c[i])
cat a.txt b.txt >c.txt似乎也可以
但是没有strip操作，不够灵活
