python flask | how to store html input in a python variable

Question

using flask in python to get html input and store it as python variable

/example.html
<form>
<input type=text name=string> # a string value
<input type=submit>
<input type=text name=float> # a float value
<input type=submit> 
</form>
/main.py
@app.route("/")
def get_input():
 example_string = request.args.get('search')
 example_limit = request.args.get('float')
 return render_template('example.html', example_string, example_limit)
/examplefile.py
from main import example_string, example_limit
print(example_string)
print(example_limit)

this particular approach does not seem to work, maybe its the request.args.get() not being used appropriately or something. You can probably see what I've tried to do here. Please help.

• Tomas Am: it makes no sense, do you want to store value from input or it's name?
• sailormoonbs: i want to get value when they click submit, so i that value can be used elsewhere in the program. so main thing is i want store the input value

Your question suggests that you may need to pass this or similar tutorial: https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

For your problem there are many ways, example route:

@app.route('/test', methods=['POST', 'GET'])
def test():
 if request.method == 'POST':
 #version 1:
 opt1 = request.form.to_dict()
 for key in opt1:
 if key == "string":
 string = opt1[key]
 if key == "float": 
 floata = opt1[key]
 print(string, floata)
 #version 2:
 string2 = request.form["string"]
 float2 = request.form["float"]
 # if you need float : floatvar = float(float2)
 print(float2)
 print(string2)
 return "success"
 else:
 return render_template('example.html')

Template:

<form method="POST">
 <input type="text" name="string"/>
 <input type="text" name="float"/>
 <button type="submit">Submit</button>
</form>
