I am trying to get the hard drive size and free space using Python (I am using Python 2.7 with macOS).
I am trying with os.statvfs("/"), especially with the following code.
Is it correct what I am doing? Which definition of the variable giga shall I use?
import os
def get_machine_storage():
result=os.statvfs("/")
block_size=result.f_frsize
total_blocks=result.f_blocks
free_blocks=result.f_bfree
# giga=1024*1024*1024
giga=1000*1000*1000
total_size=total_blocks*block_size/giga
free_size=free_blocks*block_size/giga
print("total_size = %s" % total_size)
print("free_size = %s" % free_size)
get_machine_storage()
EDIT:
statvfs is deprecated in Python 3, do you know any alternative?

For Python 2 till Python 3.3
Notice: As a few people mentioned in the comment section, this solution will work for Python 3.3 and above. For Python 2.7 it is best to use the psutil library, which has a disk_usage function, containing information about total, used and free disk space:
import psutil
hdd = psutil.disk_usage("/")
print ("Total: %d GiB" % hdd.total / (2**30))
print ("Used: %d GiB" % hdd.used / (2**30))
print ("Free: %d GiB" % hdd.free / (2**30))
Python 3.3 and above:
For Python 3.3 and above, you can use the shutil module, which has a disk_usage function, returning a named tuple with the amounts of total, used and free space in your hard drive.
You can call the function as below and get all information about your disk"s space:
import shutil
total, used, free = shutil.disk_usage("/")
print("Total: %d GiB" % (total // (2**30)))
print("Used: %d GiB" % (used // (2**30)))
print("Free: %d GiB" % (free // (2**30)))
Output:
Total: 931 GiB
Used: 29 GiB
Free: 902 GiB
