translating SQLcipher GUI to CLI (or pyhton)

Question

The question is simple

How can i turn this SQLciper GUI

Into lines of code either in SQLciper CLI or using a python module ?

Here's what i've tried (FAILED ATTEMPTS)

attempt on python using a module

c.execute("PRAGMA key='something'") 
c.execute("PRAGMA kdf_iter = 1")
c.execute("PRAGMA kdf_algorithm = PBKDF2_HMAC_SHA1")
c.execute("PRAGMA hmac_algorithm = HMAC_SHA1")
c.execute('SELECT type,name,sql,tbl_name FROM "main".sqlite_master')

attempt on SQLcipher CLI

sqlite> PRAGMA key='secretkeyhere';
sqlite> PRAGMA kdf_iter = 1;
sqlite> PRAGMA cipher_hmac_algorithm = HMAC_SHA1;
sqlite> PRAGMA cipher_kdf_algorithm = PBKDF2_HMAC_SHA1;
sqlite> .tables
