获取没有类似JSON风格的mysql python的列表

Question

I am building a POS (point of sale) in python with MySQL! I want to list all articles, but I get the JSON-like output. My code:

 import mysql.connector print('eXperience POS\\nArtikli:') posdb = mysql.connector.connect\\ ( user='root', password='', host='127.0.0.1', database='experiencepos' ) try: cursor = posdb.cursor() cursor.execute('SELECT * FROM artikli') sviartikli = cursor.fetchall() print(sviartikli) finally: posdb.close()

I think you're confusing JSON output with it printing a dict . Each item in the cursor returns a dict containing the item's fields. Since you did not show the example output I'll just use a name and description field for example. This is what I think you're looking for though. Also you may want to just loop through the cursor as printing the entire cursor would just print a list of dicts with all the items.

import mysql.connector

print('eXperience POS\nArtikli:')

posdb = mysql.connector.connect\
(
    user='root',
    password='',
    host='127.0.0.1',
    database='experiencepos'
)

try:
   cursor = posdb.cursor()
   cursor.execute('SELECT * FROM artikli')
   for sviartikli in cursor:
       name = sviartikli['name'] #example field
       description = sviartikli['description'] #another example field
       print("Name: {} Description: {}")
finally:
   posdb.close()
