storing the result of a dictionary to the database using Python (PostgreSQL)

Question

i want to insert the result from the below dictionary to the database ( i'm using PostgreSQL) :

companies_list = dict(zip(code, short_name))

the result for this dictionary after running the code and printing will show the following ( as an example ):

companies_list = { '00001': 'A', '00002': 'B', '0010': 'Z'}

so when i tried to insert the dictionary above to the database ( code ) below :

con = None
con = psycopg2.connect("dbname = 'testdb' user='user'")
cur = con.cursor()

cur.execute("CREATE TABLE companies_info(code TEXT PRIMARY KEY, short_name TEXT)")


query = "INSERT INTO companies_info ( code, short_name) VALUES ( %(code)s, %(short_name)s)"
cur.executemany(query, companies_list)

con.commit()
con.close()

i get the following:

cur.executemany(query, companies_list)
TypeError: string indices must be integers, not str

anyone can fix his error ?

Answer 1

code = ['00001', '00002', '0010']
short_name = ['A', 'B', 'Z']
companies_list = [tuple((t,)) for t in zip(code, short_name)]
query = "insert into companies_info (code, short_name) values %s"
cursor.executemany(query, companies_list)
