python读取文件中的一行有效数据

数据格式：
t1.txt

111231y211121&*dd990000  01  23 0111  993  d    984

代码：

total = []with open('t1.txt') as fd:    cur = []    Data = []    data = []    for line in fd:        line = line.rstrip()        line = line.lstrip()        cur.append(line)        if line.isdigit():            Data.append(line)            data.append(int(line))print(cur)print(Data)print(data)

结果：

['1', '1123', '1y211', '121&*dd99', '', '0000', '01', '23', '0111', '', '993', 'd', '984']['1', '1123', '0000', '01', '23', '0111', '993', '984'][1, 1123, 0, 1, 23, 111, 993, 984]
