简单地说，您希望逐行遍历文件并解析值

with open('data.bin') as f:
    for line in f:
        parts = line.split() # split the line on whitespace
        if parts[0] == 'mlon': # whatever variable you want to process
            a = int(parts[1]) # convert next two params from strings to integers
            b = int(parts[2])
            desc = ' '.join(parts[2:]) # join the rest back together as the description
            print(a, b, desc)
