Answer 1

如果您只需要第一行（例如获取标题），那么这应该可以做到：

with open('file.txt', 'rb') as f:
    print f.readline().split()

Answer 2

假设f被实例化为open("file.txt", "r")，那么您就是在文件上迭代的普通Jane。你知道吗

如果只需要第一行之后的元素，请尝试以下构造：

with(open("file.txt", "r")) as f:
    li = f.readlines()
    for line in li[1:]:
        print line.split()
