it fixes the issue I just looked through your code, its seems pretty well written.
That last commit where you tried to implement it has created a subtle bug:

Scanning through 2d boolean array to find closest true coordinate


Tag : java , By : Killercode
Date : March 29 2020, 07:55 AM
should help you out I am using a 2 dimensional boolean array to check where an entity is inside of my 2D side scroller as well as for collision. I know I am not looking for how high or low an entity away is and that is intentional. When I run this code it says the closest entity is 15 cells away. However, when I run my code it says the closest entity away is 15 blocks. Also when I print out distanceX it prints out the following: 9 0 0 2 2 15 9 0 0 2 2 15. I don't know why it won't register 9 as the closest even though that's is the first closest distance it recieves.
Long distance = Long.MAX_VALUE;

I wish did fix the issue. I'm creating an ionic app and there are variables I request from a php page through the Ionic controller. From the variables I get, I have a field called active which either be yes or no for each user after log on. What I want to achieve is, there is a div on the page called "activediv" and I want that div show only if the variable from the json = yes. , Try this
<div id="activediv" ng-if ="item.active == 'yes'">{{item.active}}</div>

Python select data return boolean true-false and DELETE value true

I wish this helpful for you This error is related to inconsistent indentation. Python relies on indentation to determine when "code blocks" start and stop. Take a look at this for more details.
Try something like this:
#!/usr/bin/python
import mysql.connector

conn = mysql.connector.connect(host="lll",user="ppp",passwd="ppp",db="ppp")
cursor = conn.cursor()

cursor.execute("SELECT(case when user1 = '1' THEN 'true' ELSE 'false' END) AS IsEmtpy from dt")
print(cursor.fetchall())

try:
  if True:
    cursor.execute("DELETE FROM dt WHERE user1='1'")
    print "DELETE SUCESS"
  else:
    print "DELETE ERROR"
    conn.commit()

except Exception as e:
  conn.rollback()

conn.close()

example.approved.to_s.upcase
def data
  examples.map do |example|
    [
      example.approved.to_s.upcase,
      example.updated_at.strftime("%m/%d/%Y at %I:%M%p")
    ]
  end
end
