Python Module that stores variables in a file to allow variable storage after script is terminated
Project description
QuickVars
Python 3 variable storage module centered around the in-built
pickle module.
This module contains 3 functions: “QuickVars.setVar()”,
“QuickVars.getVar()”, and “QuickVars.delVar()”.
Though very self-explanitory, more details on each function are below.
QuickVars.setVar(key, val, t = ‘data’)
@param key : The key param is used as the key in a Dictionary, choose your datatype accordingly. @param val : The val param takes the data stored under the key, and can be any Dictionary compatible value. @param t : The t param chooses the file to store the key-value pair in. @returns : Dictionary containing values stored in the file. The setVar function will take a minimum of two params (key, val), and has an optional param (t). The key-value pairs will be added to an encoded (Please note: Strictly speaking it is not encrypted and should not be considered safe to store valuable information) JSON file at: "data/{Script Name Without Extension}_{t}.dat".
QuickVars.getVar(key, t = ‘data’)
@param key : The key to search for in stored dictionary. @param t : The t param chooses the file to search for the key-value pair in. @returns : Stored Value (May be one of many data types). The getVar function will take a minimum of one param (key), and has an optional param (t). The function will search the chosen files dictionary for the key and return it if found, otherwise return 'None'.
QuickVars.getAllVars(t = ‘data’)
@param t : The t param chooses the file to get all vars from. @returns : All values stored in specified file The getAllVars function will take a an optional param (t). The function will return all values in the specified file.
QuickVars.delVar(key, t = ‘data’)
@param key : The key to remove from stored dictionary. @param t : The t param chooses the file to search for the key-value pair in. @returns : Stored Dictionary after attempting to remove indicated key. The delVar function will take a minimum of one param (key), and has an optional param (t). The function will search the chosen files dictionary for the key and delete it if found, returning the dictionary.
Examples
import QuickVars as QV lst = [] for (i in range(20)): lst.append(i) QV.setVar('test', lst) # Returns: {'test': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]} print(QV.getVar('test')) # Outputs: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19] QV.setVar('test1', '5*9.2=' + str(5*9.2)) # Returns: {'test': [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19], 'test1': '5*9.2=46.0'} QV.setVar('test', 'different value here!', 'foo') # Returns: {'test': 'different value here!'} QV.delVar('test', 'data') # Return: {'test1': '5*9.2=46.0'}
