Python Pickle Module Usage __python

Using Python's built-in modules to save, extract data structure objects in Python:

such as lists, dictionaries, collections, and so on.

First import the Pickle module (no installation required):

Import Pickle

To save dictionary data using pickle:

Output_2_3 = open (' P2c_2_3.pkl ', ' WB ')
pickle.dump (P2c_2_3, Output_2_3)
output_2_3.close ()

P2c_2_3 is one of my dictionaries.

Save it as

P2c_2_3.pkl

File

Use pickle to extract saved data:

P2C23_PKL = open (' p2c_2_3.pkl ', ' RB ')
P2c_2_3 = Pickle.load (P2C23_PKL)

Variable meaning ditto

After extraction, you can set the

P2c_2_3

Use as a dictionary directly

Other data types are saved using pickle, and the extraction method is similar to the above.
