I'm getting error while open my app after using pyinstaller before using pyinstaller when the app still in .py it's working 100%
after that I'm getting this error

I am on windows 10 and using python3.9.
I installed the pagkage
>python3 -m pip install mysql-connector-python
Now I try to run a simple program
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="root",
password="",
database="pythonDB"
)
mycursor = mydb.cursor()
mycursor.execute("SELECT * FORM customers")
myresult = mycursor.fetchall()
for x in myresult:
print(x)
I am getting the following error when running

try these:

basically change the import to
from mysql import connector
Seems like the Python3 is not taking SQL directly inside the execute function.
Assign the query to a variable and pass it to the execute() function.
It worked for me!!!
sql = "SELECT * FROM customers"
mycursor.execute(sql)
Also try try renaming the file if it is something like select.py to select_customers.py
I'm trying to take recipe hyperlinks from a pre-existing file and add them to a table in a database. I have already created the database and given the file name to set up a connection and insert the data into the table but whenever I do so I get the error sqlite3.OperationalError: unable to open database file.
Here's my code:
import bs4, os, requests, time
import sqlite3
from flask import current_app, g
def create_connection(db_file):
db = sqlite3.connect(db_file)
c = db.cursor()
return db
def get_html():
'''
Get the BBC Food sitemap and save it to a local file.
'''
page = None
db = create_connection("pantry/instance/flaskr.sqlite")
for attempt in range(1, 4):
print("line 40")
page = requests.get('http://www.bbc.co.uk/food/sitemap.xml')
try:
page.raise_for_status()
break
except requests.RequestException:
time.sleep(attempt * 10)
if not page:
raise Exception('Failed to get sitemap.xml')
sitemap = bs4.BeautifulSoup(page.text, 'html.parser')
# Write the recipe urls to a text file
print("line 53")
for line in sitemap.find_all('loc'):
for string in line.stripped_strings:
if string.startswith('https://www.bbc.co.uk/food/recipes/'):
print("line 57")
recipeUrl = string
if (
db.execute("SELECT recipeID FROM recipe WHERE weblink = ?", (recipeUrl,)).fetchone()
is not None
):
error = "recipe weblink {0} is already inputted.".format(recipeUrl)
if error is None:
db.execute(
'INSERT INTO recipe (weblink) VALUES (?)',
recipeUrl
)
db.commit()
db.close()
And the error message:

sqlite3.OperationalError: unable to open database file
Based on the consoles error report, your .py file is located in: C:/Users/Eva Morris/PycharmProjects/pantry/flaskr/BBCscraper/scraperecipes.py".
In your code you set your databases directory using the relative path as:pantry/instance/flaskr.sqlite.
This means python is looking for the directory: C:/Users/Eva Morris/PycharmProjects/pantry/flaskr/BBCscraper/pantry/instance/ to create/link your database file in.
If that is not a preexisting directory, sqlite3.connect will not be able to create your database flaskr.sqlite.
You may need to update the code db = create_connection("pantry/instance/flaskr.sqlite") to something like db = create_connection("flaskr.sqlite") which should work without any problem since it will just create the database in your working directory.
While connecting to Hive2 using Python with below code:

with conn.cursor() as cur:
#Show databases
print cur.getDatabases()
#Execute query
cur.execute("select * from table")
#Return column info from query
print cur.getSchema()
#Fetch table results
for i in cur.fetch():
print i
I am getting below error:

thrift_sasl.py is trying cStringIO which is no longer available in Python 3.0. Try with python 2 ?
You may need to install an unreleased version of thrift_sasl. Try:
pip install git+https://github.com/cloudera/thrift_sasl
If you're comfortable learning PySpark, then you just need to setup the hive.metastore.uris property to point at the Hive Metastore address, and you're ready to go.
The easiest way to do that would be to export the hive-site.xml from the your cluster, then pass --files hive-site.xml during spark-submit.
(I haven't tried running standalone Pyspark, so YMMV)
I am trying to use Hive/Hadoop using python.

Can someone tell me how to go about this?
I am trying to execute the following code:
import MySQLdb
import MySQLdb.cursors
conn=MySQLdb.connect(host = '127.0.0.1',
user = 'root',
passwd = 'root',
db = 'test',
cursorclass = MySQLdb.cursors.DictCursor)
cursor=conn.cursor()
But it gives me the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build/bdist.linux-x86_64/egg/MySQLdb/connections.py", line 243, in cursor
AttributeError: 'Connection' object has no attribute 'cursorclass'
Why is this?
import MySQLdb
import MySQLdb.cursors
conn=MySQLdb.connect(host = '127.0.0.1',
user = 'root',
passwd = 'root',
db = 'test',)
cursor=conn.cursor(cursorclass = MySQLdb.cursors.DictCursor)
This is a rough hack, but it may not be advisable to use it. The script with throw out dictionary object by default but the application might require an tuple or array.
