from collections import Counter
L = []
with open('F:/python/test.txt', 'r') as f:
    for line in f.readlines():
        L.append(line.strip())
with open('F:/python/test2.txt', 'w', encoding='utf-8') as f1:
    for x, y in Counter(L).items():
        st = x + '次数' + str(y) + '\n'
        f1.write(st)

这样???
