I'm running a flask server, with a textbox input and a while loop (in a different thread). I want to pass the input value from the textbox to the while loop.
This is the .py code: -
from flask import Flask, render_template, request
-
import thread
-
import time
-
-
app = Flask(__name__)
-
def main():
-
-
while True:
-
time.sleep(5)
-
print "var = "+str(var)
-
-
@app.route("/")
-
def index():
-
-
templateData = {
-
'var': var
-
-
}
-
return render_template('index.html', **templateData)
-
-
@app.route('/', methods=['POST'])
-
def post():
-
-
global var
-
var = 0
-
var = int(request.form['var'])
-
return str("var: " + str(var))
-
-
if __name__ == "__main__":
-
thread.start_new_thread(main, ())
-
thread.start_new_thread(post, ())
-
app.run(host='0.0.0.0', port=8083, debug=True)
-
This is the .html code: -
<!DOCTYPE html>
-
<head>
-
<title>POST</title>
-
</head>
-
<body>
-
<form method="POST">
-
var:<br>
-
<input name="var">
-
<br><br>
-
Current: {{ var }} <br><br>
-
<input type="submit">
-
</form>
-
</body>
-
</html>
-
I don't know what is the proper way to get the value to the while loop, because I'm getting mixed signals in the loop. If I for example write 3 in the textbox I'll get... -
var = 0
-
var = 3
-
var = 0
-
var = 3
-
var = 0
-
var = 3
-
var = 0
-
var = 3
-
...in the while loop, because it's first reading var = 0 and then var = int(request.for m['var'])

If you are not familiar with the halting problem, I will not go into
it in detail but it states that it is impossible to write a program
that can tell if a loop is infinite or not. This is a fallacy built
on the assumption of mythical infinite all powerfull machines. In
reality we deal with finite machines that are capable of two states in
a loop, they either terminate, or repeat themselves. In the mythical
halting problem scenario...

Hi All,
I copied a script example from http://www.irt.org/script/640.htm into

(in an infinite loop, I think) when I previewed the example.
On the off chance that example exposed a weakness in HTML-Kit, I ran
the example in IE7, which also hung.
The example seems to start an infinite loop which the user should be

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
