Unable to insert data in PostgreSQL 11.0 table - postgresql

Question

I would like to insert values into postgresql 11.0 table. However, when I am trying to do that I am getting following error:
TypeError: not all arguments converted during string formatting
I am running following code:
#CREATE TABLE
try:
connect_str = "dbname='xx' user='xx' host='xx' " "password='xx' port = xx"
conn = psycopg2.connect(connect_str)
except:
print("Unable to connect to the database")
cursor = conn.cursor()
cursor.execute("""DROP TABLE IF EXISTS tbl""")
try:
cursor.execute("""
CREATE TABLE IF NOT EXISTS tbl(
entry_id CHARACTER VARYING NOT NULL,
name CHARACTER VARYING NOT NULL,
class CHARACTER VARYING NOT NULL,
ko_id CHARACTER VARYING NOT NULL,
PRIMARY KEY (entry_id))
""")
except:
print("The table cannot be created!")
conn.commit()
conn.close()
cursor.close()
#INSERT DATA INTO TABLE
try:
connect_str = "dbname='xx' user='xx' host='xx' " "password='xx' port = xx"
conn = psycopg2.connect(connect_str)
except:
print("Unable to connect to the database")
cursor = conn.cursor()
with open ('file.txt') as f:
for line in f:
if re.match('^[A-Z]+',line) and line.startswith("ENTRY") or line.startswith("NAME") or line.startswith("CLASS") or line.startswith("KO_PATHWAY"):
key, value = line.split(" ", 1)
#print (key, value)
if key == "ENTRY":
cursor.execute("INSERT INTO tbl (entry_id) VALUES (%s)",('value'))
conn.commit()
conn.close()
cursor.close()
The key-value looks like this:
ENTRY map00010 Pathway
NAME Glycolysis / Gluconeogenesis
CLASS Metabolism; Carbohydrate metabolism
KO_PATHWAY ko00010
ENTRY map00011 Pathway
NAME Glycolysis
CLASS Metabolism; Carbohydrate
KO_PATHWAY ko00011
The value map00010 Pathway and map00011 Pathway should be inserted in the table and create two rows.
Any help is highly appreciated.
