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
