How can you use SQL queries on pydroid app?

# This code demonstrates a SQLite connection on Android.
# You can use it in the Code Playground or another app like Pydroid3.

import sqlite3
conn = sqlite3.connect('pythonexample.db')
# If running in Pydroid, the above will save to the Pydroid directory on your device
# You could also specify a folder on your device if you have permission to save there. For example:
# conn = sqlite3.connect('/storage/emulated/0/Download/pythonexample.db')
# Change the above to whatever your download folder is on your device. You'll usually have permission to write there on Android.

c = conn.cursor()

# Create a table
c.execute('''CREATE TABLE trainingclass
             (sitename text, classname text, classrating text, userscore real)''')

# Insert a row of sample data
c.execute("INSERT INTO trainingclass VALUES ('Sololearn','Python','5 Stars',70.12)")

# Save the changes
conn.commit()

t = ('Python',)
c.execute('SELECT * FROM trainingclass WHERE classname=?', t)
print(c.fetchone())

# Close the connection
conn.close()

# After running this code, I was able to open the database from a SQLite client on Android.
