(This post was last modified: Apr-10-2022, 08:31 AM by menator01.)
I like the post from here and thought I would give it a try using tkinter.
Only got a basic text version at the moment. Uses a json file for the database.
I will probably break the search function down into three separate methods when I get ready to apply it to a tkinter gui.
Planning on adding a add and delete button as well. Anyhow here is my attempt at a search for the characters.
json file
{
"wizard": [
{
"name": "ralph",
"age": 20,
"spells": {"fireball": 10, "firestorm": 15}
},
{
"name": "george",
"age": 20,
"spells": {"firestorm": 15, "meteor": 30}
}
],
"cleric": [
{
"name": "fred",
"age": 18,
"spells": {"heal": 5, "heal all": 12}
}
]
} python file
import json
# Get json file
file = "character.json"
# Open json file and load
with open(file, 'r') as rfile:
data = json.load(rfile)
# Define function for searching and returning data
def search(term=None, card=None):
# If card == name, we're seaching by name
if card == 'name':
# Create an empty return list
ret = []
# Get key, value pair from json file
for info, stat in data.items():
# Loop over stat to find the name and append to mylist all data related
for item in stat:
if item['name'] == term.lower():
ret.append(f'character type: {info}')
mylist = [item for item in item.items()]
# The list has dict, so we loop over and format the dicts then append to
# the ret list along with data that is not a dict
for items in mylist:
tmp = []
if isinstance(items[1], dict):
for key, value in items[1].items():
tmp.append(f'{key}: {value}')
string = ', '.join(tmp)
ret.append(f'{items[0]}: {string}')
else:
string = f'{items[0]}: {items[1]}'
ret.append(string)
# Elif the card is a guild search, we loop over the json file and return all
# data for that character type
elif card == 'guild':
ret = []
for items in data[term]:
ret.append(f'character type: {term}')
tmp = []
for key, val in items.items():
if isinstance(val, dict):
for item, strength in val.items():
tmp.append(f'{item}: {strength}')
string = ', '.join(tmp)
ret.append(f'{key}: {string}')
else:
string = f'{key}: {val}'
ret.append(string)
# Else we want to return all characters
else:
ret = []
for _type, stats in data.items():
for items in stats:
ret.append(f'character type: {_type}')
tmp = []
for item, stat in items.items():
if isinstance(stat, dict):
for key, val in stat.items():
tmp.append(f'{key}: {val}')
string = ', '.join(tmp)
ret.append(string)
else:
string = f'{item}: {stat}'
ret.append(string)
return ret
# Displays all characters
# i = 0
# for items in search():
# print(items)
# if i > 2:
# print()
# i = 0
# else:
# i += 1
# Returns all guild type characters
card = search('cleric', 'guild')
i = 0
for items in card:
print(items)
if i > 2:
print()
i = 0
else:
i += 1
# Returns single character data
# card = search('fred', 'name')
# for data in card:
# print(data) Output: character type: cleric
name: fred
age: 18
spells: heal: 5, heal all: 12

Here is one of the re-wites. This is my backend.py
Soon I will start writing the classes to use the functions.
Any thoughts much appreciated.
import json
import os
# json file
file = 'card.json'
# Check if card.json exists. If not create it
if os.path.exists(file):
pass
else:
with open(file, 'w') as out_file:
characters = {}
json.dump(characters, out_file, indent=4)
# Function for creating classes
def create_class(file, character_class):
'''
Function checks the json file for already existing classes.
If one exist it return a message. If one does not exist it
will create the class
'''
with open(file, 'r+') as json_file:
data = json.load(json_file)
if character_class in data:
print('Class already exists')
else:
data[character_class] = []
json_file.seek(0)
json.dump(data, json_file, indent=4)
print(f'Class {character_class} created')
def create_character(file, character):
'''
This function will create a character for a chosen class.
It will check if the entered name exist. If it exists a
message is returned. Other wise the character is created
'''
with open(file, 'r+') as json_file:
data = json.load(json_file)
add_character = True
for info in data[character[0]]:
if character[1]['name'].lower() in info.values():
add_character = False
print(f'{character[1]["name"].title()} already exists in the database.')
if add_character:
data[character[0]].append(character[1])
json_file.seek(0)
json.dump(data, json_file, indent=4)
print(f'{character[1]["name"].title()} has been created.')
def delete_character(file, name):
'''
This function searches for a entered name and if it
exist, will be deleted
'''
with open(file, 'r+') as json_file:
data = json.load(json_file)
for _ in data:
for i in range(len(data[_])-1):
if name.lower() == data[_][i]['name']:
data[_].pop(i)
with open(file, 'w') as json_file:
json.dump(data, json_file, indent=4)
print(f'character has been deleted.')
def get_character(file, name):
'''
This function will return all related data to a character entered.
'''
with open(file, 'r+') as json_file:
data = json.load(json_file)
for _ in data:
for i in range(len(data[_])):
if name.lower() == data[_][i]['name']:
character = data[_][i]
return _, character
return f'{name.title()} does not exist.'
# def update_character(file, old_character, name, age, skills):
def update_character(file, *args, **kwargs):
'''
This function will update a created character.
It gets the old character by name and stores the data in
a variable to be compared and updated with the new data.
The old character is deleted and a new one created from
the new updated data.
'''
character = old[1]
guild = old[0]
name = old[1]['name']
character.update(new[1])
character = (guild, character)
delete_character(file, name)
create_character(file, character)
print('character has been updated.')
'''
The coding below is what I been using to test the functions
'''

# new = ('wizard', {'name':'tabol', 'age': 27, 'skills':{'firestorm':90, 'fireball': 20}})
# update_character(file, old, new)
# print(get_character(file, 'tony'))
# delete_character(file, 'tony')
# character = (
# 'wizard',
# {
# 'name': 'tony', 'age': 24, 'skills':{'fireball': 10, 'meteor': 8}
# })
#
# create_character(file, character)
# create_class(file, 'wizard')
# create_class(file, 'cleric')
# create_class(file, 'warrior')

Think I got the model and backend part setup. Now I'll start tackling the view and contoller part.
Re-wrote the backend a little.
Updated code. As always I welcome feedback.

I think this will be my final version for now.
I have tried to optimize the code a little.
Everything seems to work. The spells section doesn't use a dict anymore. Just a string.
Anyhow here is the code

pass
