###7.4.2 实例:BikeStock模块的类 BikeStock模块使用BinaryRecordFile.BinaryRecordFile来提供一个简单的仓库控制类,仓库项为自行车,每个由一个BikeStock.Bike实例表示,整个仓库的自行车则存放在一个BikeStock.BikeStock实例中。BikeStock.BikeStock类将字典(其键为自行车ID,值为记录索引位置)整合到BinaryRecordFile.Bina...

在不知道pdf.write和send_file函数的确切细节的情况下,我希望在这两种情况下,它们都会采用符合Binaryo接口的对象。因此,您可以尝试使用字节码将内容存储在in-memory缓冲区中,而不是写入文件: with io.BytesIO() as buf: pdf.write(buf) buf.seek(0) send_file(data=buf, filename=filename) 根据above-mentio...
functions such as writerow(). The savetxt saves a 1D or 2D array to a text file, The tofile() writes array data to a file in binary format, The writer() writes a single row to the CSV file, and the to_csv() writes a pandas DataFrame to a comma-separated values (csv) file...
