from flask import Flask , render_template
from flask_script import Manager
from wtforms import StringField
import os


#Launching Server
app = Flask(__name__)
manager = Manager(app)


#Settings..!
PEOPLE_FOLDER = os.path.join('static', 'people_photo')
app.config['UPLOAD_FOLDER'] = PEOPLE_FOLDER




#Defining URL's And Rendering!
@app.route('/index')
def index():
   full_filename = os.path.join(app.config['UPLOAD_FOLDER'], 'lkj.jpg')
   return render_template("index.html", user_image = full_filename)


@app.route('/user/<name>')

You can wrap your input into a form and submit it to the /user view.

<form action="/user"> 
  <input type="text" id="username" name="username" maxlength="10"><br><br>
  <button type="submit" name="button">Submit</button>
</form>

then in your view function

@app.route('/user')
def user():
   who = request.args.get('username')
   # Do something with who
   return render_template("user.html", name=who)

I am not sure what exactly you mean. This will redirect to www.example.com/user?username=<who>
