怎样用python提取第一组数据再放到第二组当中呢？

Answer 1

a = '''
mon    1    2    3
       2    2    2
tue    1    2    3
       2    2    2
'''

name = ''
al = []
for d in a.split('\n'):
    dl = d.split('   ')
    if len(dl) > 1:
        if dl[0]:
            name = dl[0]
        else:
            dl.pop(0)
            dl[0] = name
        al.append('   '.join(dl))
print '\n'.join(al)
