I have a list:
imageList = [(cloud/image_stored_docker:1.1.0, tarfile-1.1.0.tar),
(cloud/image_stored_docker:1.2.0, tarfile-1.2.0.tar)]
I need to split in two lists, one list with keys (where images are keys) and other one with values (tarfiles).
I am trying to create a string and then convert it to list
for key, value in imageList.items():
images = images + key + ","
images = list(images)
but I get this message:
for key, value in imageList.items():
AttributeError: 'list' object has no attribute 'items'
I tried other way; removing items()
function and this is the message:
for key, value in imageList:
ValueError: too many values to unpack (expected 2)
Removed fluff at end.\
if you just want to print a list of the keys you can use a list comprehension and iterate over the tuples
imageList = [("cloud/image_stored_docker:1.1.0", "tarfile-1.1.0.tar"), ("cloud/image_stored_docker:1.2.0", "tarfile-1.2.0.tar") ]
keys = [pair[0] for pair in imageList]
print(",".join(keys))
OUTPUT
cloud/image_stored_docker:1.1.0,cloud/image_stored_docker:1.2.0
