for row in reader: print(row) file.close() 五、将数据写入内存 除了将数据写入到一个文件以外,我们还可以使用代码,将数据暂时写入到内存里,可以理解为数据缓冲区。Python中提供了StringIO和BytesIO这两个类将字符串数据和二进制数据写入到内存里。

’number‘: 数值类型(整数和浮点数) 默认情况下,如果 include 和 exclude 都为 None,则返回所有列。如果指定了 include ,则只返回包含在该列表中的数据类型的列。如果指定了 exclude ,则返回除了在该列表中的数据类型的列之外的所有列。 df = pd.DataFrame({'a': [1, 2, 3], 'b': [1.1, 2.2, 3.3...
