I developed a code in python that:
- add name, age and Id information for each person,
- search a person by name, if it exists then display a message "Found" and fill "age" and "Id" with the corresponding information, else display "not found" and fill "age" and "Id" with "---". In case of more that one name is found then a wxchoice lists all these names, after the user can choose one item in the list, then all information (age and id) related to that chosen name appears.
Note that all information are stored in a json file called "data.json".
I need to know if that is the correct way (easy to maintain, optimised, respects good practice ...) to implement that requirements:
Find below the code:
import json
import os
import wx
import wx.xrc
class ManageJson:
def __init__(self, jsonfile):
self.jsonfile = jsonfile
self.content = {"Info": []}
def read(self):
if self.isempty() is False:
with open(self.jsonfile, 'r') as infile:
self.content = json.load(infile)
def write(self):
with open(self.jsonfile, 'w') as outfile:
json.dump(self.content, outfile, indent=4)
def isempty(self):
return os.stat(self.jsonfile).st_size == 0
def Presearch(self, pattern):
return [data for data in self.content["Info"] if pattern in data['Name'] and pattern != '']
def Postsearch(self, pattern):
return [data for data in self.content["Info"] if pattern == data['Name'] and pattern != '']
def add(self, *arg):
self.content["Info"].append({"Name": arg[0], "Age": arg[1], "Id": arg[2]})
class ManageGui(ManageJson):

super().__init__(jsonfile)
def exporttojson(self, *arg):
name = arg[0]
age = arg[1]
Id = arg[2]
statusbar = arg[3]
data = super().Presearch(name.GetValue() )
if name.GetValue() != '' and age.GetValue() != '' and Id.GetValue() != '':
if len(data) == 0 and name.GetValue() != '':
if super().isempty() is False:
super().read()
super().add(name.GetValue(), age.GetValue(), Id.GetValue())
super().write()
statusbar.SetStatusText("Exporting done!")
else:
statusbar.SetStatusText("Element is already exist!")
else:
statusbar.SetStatusText("One field is empty!")

super().read()
def Presearch(self, *arg):
super().read()

print(data)
print(len(data))
if len(data) == 1:
arg[4].Clear()
f = data[0]
arg[0].SetValue(f["Name"])
arg[1].SetValue(f["Age"])
arg[2].SetValue(f["Id"])
arg[3].SetStatusText("Found")
arg[4].Append(f["Name"])
elif len(data) > 1:
arg[4].Clear()
for i in range(len(data)):
f = data[i]
arg[4].Append(f["Name"])
arg[3].SetStatusText("More than one found, choose one?")
else:
