Python擅长处理特别大的文件吗，python擅长处理,Python处理文件只能

尝试配合使用yield和read([size])

def read_in_chunks(file_object, chunk_size=1024):    """Lazy function (generator) to read a file piece by piece.    Default chunk size: 1k."""    while True:        data = file_object.read(chunk_size)        if not data:            break        yield dataf = open('really_big_file.dat')for piece in read_in_chunks(f):    process_data(piece)

可以用readlines()，返回生成器。

for line in open('file','r').readlines():    print(line)

文件大的时候可以用read([size])指定大小，然后联系读取。
