[英]Python: does gzip write to disk when opening a file for read?
I am writing a program that reads .gz archived log files from an SD card. 我正在编写一个程序,可以从SD卡读取.gz存档日志文件。 If I open a .gz archive for reading using the gzip library, will it write a temporary copy to the SD card (I don't want it to), or does it decompress the file in RAM?
如果我打开一个.gz归档文件以使用gzip库进行读取,它会向SD卡写入一个临时副本(我不希望这样做),还是将其解压缩到RAM中的文件?
You didn't show how exactly you're doing it, but if you are using gzip.open()
and read()
, then there are no temporary files. 您没有显示操作的精确程度,但是如果使用的是
gzip.open()
和read()
,则没有临时文件。 It is decompressed in memory. 它在内存中解压缩。
