Thank you very much. I have not been aware that pickle can also do the
job without a file!
Here's the complete scenario for writing and reading the data...
APPENDIX:
import pickle
import zipfile
def test1():
print("test1...")
# create data
data = {}
data["first name" ] = "Thomas"
data["second name"] = "Lehmann"
data["hobbies" ] = ["programming python"]
print (data)
# pickle data
pickleString = pickle.dumps(data)
# save string to zip under a name
file = zipfile.ZipFile("ZippedPickle.zip", "w",
zipfile.ZIP_DEFLATED)
file.writestr("some data", pickleString)
file.close()
def test2():
print("test2...")
file = zipfile.ZipFile("ZippedPickle.zip", "r",
zipfile.ZIP_DEFLATED)
# reading zipped string store under a name
pickleString = file.read("some data")
# unpickle string to original data
data = pickle.loads(pickleString)
print (data)
file.close()
if __name__ == "__main__":
test1()
test2()
