How to build a flask app on 'Google colab' for an NLP prediction?

I worked on an NLP project that can extract information from a resume like Name, Skills, Email, Designation etc. I built the project using Regular Expressions & stored the predictions in a variable.

What I have tried:

My prediction variable 'Candidate Details' looks like this --->

Candidate_Details= {"Name":data['name'], "Mobile No.":data['mobile_number'],"Email":data['email'],"Skills":t_skills,"University":unimatches, "Degree":education, "Experience in years":exp_match,"Companies_Worked@":comp_un, 'Designation':des_un, "No. of pages":data['no_of_pages']};

Now I want to build a Flask app for this. I'm writing the code for it on Google Colab. I don't understand how to go about it. Haven't found any resources online on this. The available ones show a simple HTML file. Please guide me through this.
