import string fp = open('test1.txt') a = fp.read() fp.close() fp = open('test2.txt')
b = fp.read() fp.close()
fp = open('test3.txt','w')
l = list(a + b) l.sort()
s = ''
s = s.join(l)
fp.write(s)
fp.close()
python3 方案:

with open('test1.txt') as f1, open('test2.txt') as f2, open('2.txt', 'w') as f3:
for a in f1:
b = f2.read()
c = list(a + b) c.sort()
d = ''
d = d.join(c)
f3.write(d)
