可以简单的看出,数据一共有 5000000 行 7 列,其中 2列是 int64,2 列是 float64 ,3 列是 object,这里显示的内存占用只是一个近似占用,如果要获得更精确的内存使用情况,需要设置参数(memory_usage='deep'),结果如下,精确的内存占用为 1.1 G RangeIndex: 5000000 entries, 0 to 4999999 Data columns (total ...

As you can see, we get the size of the file which is in bytes. To convert the bytes into megabytes, we need to divide the size by (1024 *1024) as shown below. ADVERTISEMENT python # get size of file in Pythonfile_size = os.path.getsize('bitcoin_csv.csv')/(1024*1024)# printing...
When you call a foreign function that takes arguments, ctypes converts Python data types to their C counterparts and then the other way around before returning the result to Python. This conversion can become costly, especially when you deal with larger data volumes or more complex data ...
Then, before writing it back to a WAV file, you’ll convert and clamp the value to make it fit the desired range. The 8-bit integer encoding is the only one relying on unsigned numbers. In contrast, all remaining data types allow both positive and negative sample values. Another ...
The program will convert the data in MegaBytes(MB) to bytes, kilobytes(KB), GigaBytes(MB), or TerraBytes(TB), depending on the user’s selection rounded to six decimals. Here are the specific requirements: Write a void method named menu_firstNam...
Unicode data is usually converted to a particular encoding before it gets written to disk or sent over a socket. It’s possible to do all the work yourself: open a file, read an 8-bit byte string from it, and convert the string with str(bytes, encoding). However, the manual approach...
