python怎么读取文本文件? python读取文件内容？文件的读取 步骤：打开 -- 读取 -- 关闭>>> f = open('/tmp/test.txt') >>> f.read() 'hello python!\nhello world!\n' >>> f.close() 读取数据是后期数据处理的必要步骤

处理上传的文件：f1 = request.FILES['pic']fname = '%s/%s' % (settings.MEDIA_ROOT, f1.name)with open(fname, 'w') as pic:for c in f1.chunks():pic.write(c)测试报错：TypeError at /upload/write() argument must be str,
