How to get the total sum of sizes of all packages in a Python requirements.txt file? Or a pip freeze.
I want to figure out how much space all packages take up. I know this exists but it doesn't show how to get the sum.
Slightly adapting @Tirtha answer from the link you provided, here is a version also displaying the total size of all packages:
import os
import pkg_resources
def calc_container(path):
total_size = 0
for dirpath, dirnames, filenames in os.walk(path):
for f in filenames:
fp = os.path.join(dirpath, f)
total_size += os.path.getsize(fp)
return total_size
dists = [d for d in pkg_resources.working_set]
total_size = 0
for dist in dists:
try:
path = os.path.join(dist.location, dist.project_name)
size = calc_container(path)
if size/1000 > 1.0:
print (f"{dist}: {size/1000} KB")
print("-"*40)
total_size += size/1000
except OSError:
"{} no longer exists".format(dist.project_name)
print("="*40)
print(f"Total size of all packages: {round(total_size, 2)} KB")
