Python 字符串魔法三之 expandtabs用法

#expandtabs，断句20,\t表示从这里断，然后expandtabs补齐到20个字符，\n则换行
s = "12345678\t9"
v = s.expandtabs(6)
print(v,len(v))

test = "username\temail\tpasswd\nzhangzhenxian\t13798494919@qq.com\t123\nxiaoming\t159798968@qq.com\t123 "
v = test.expandtabs(20)
print(v)

运行后:

 username            email               passwd
 zhangzhenxian       13798494919@qq.com  123
 xiaoming            159798968@qq.com    123
