Try to make a WEB application for phone book with flask Part 1 (Connection with SQLITE, displayed in Flask) Try to make a WEB application for phone book with flask Part 2 (How to handle POST and GET in Flask) Try to make a WEB application for phone book with flask Part 3 (Add registration form) Try to make a web application for phone book with flask Part 4 (Add search form)

Now that we have a registration window, we will combine it and create a search form.

How to search

SELECT (column) FROM (table name)　WHERE (検索するcolumn)  =(equal) or LIKE "(String)"

Just use SQLITE string search as it is. For some reason I couldn't do FTS (full-text search) in my environment, so I can't search by name only.

With this, I was able to implement all the necessary functions.

But ...

app.py

What is this ...

It doesn't even become a WEB application ...

I decided to remake it from the next time.
