Python中的shutdownil模块中的shutil.move（）方法

Question

Does shutil.move(src, dest) method call the os.system() method or the bash commands 'mv' and 'cp'?

PS : I searched on the net but couldn't find any helpful info.

Answer 1

use the source Luke:

http://hg.python.org/cpython/file/2.7/Lib/shutil.py

it actually does neither. if you follow the code, it ends up opening a new file descriptor and writing buffered bytes to it. like this:

while 1:
    buf = fsrc.read(length)
    if not buf:
        break
    fdst.write(buf)
