Question

1) A route with the relative URL /vowels/<some_string> where <some_string> is the argument that the user specifies in the address bar of the browser on the client side. The flask application should count the number of vowels in the some_string and return a message that includes the vowel count as an h1 heading in html. For instance, if some string is abracadabra, the string "abracadabra contains 5 vowels" should be displayed in the browser. 2) A route with relative URL /sum_digits/<some_integer> where <some_integer> is the argument that the user specifies. The flask application should add the digits and return the sum as an h1 heading in html. For instance, if some_integer is 234, the string "The sum of the digits in 234 is 9". You may assume that the user will provide valid input.

Answer 1

Note:-please store html files in templates folder

Code:-

from flask import Flask,redirect,url_for,request,render_template
app=Flask(__name__)
@app.route('/vowels/<string>')
def vowels(string):
count=0
for i in string:
if i=='a' or i=='e' or i=='i' or i=='o' or i=='u':
count+=1
return render_template('index.html',word=string,n=count)

@app.route('/sum_digits/<int:integer>')
def int_count(integer):
num=integer
count=0
while(num>0):
count=count+num%10
num=num//10
return render_template('index2.html',number=integer,n=count)
if __name__=='__main__':
   app.run()
