SQL query with a syntax error with DATE_ADD() function (edited) - mysql

Question

I'm writing some SQL queries, and an error occurred:
psycopg2.errors.SyntaxError: syntax error at or near "1"
LINE 10: ... AND A2.block_time < DATE_ADD(A1.block_time, INTERVAL 1 DAY)
My query where the error occurred is:
SELECT address_id
FROM address_history A1
WHERE EXISTS (
SELECT *
FROM address_history A2
WHERE A1.address_id = A2.address_id
AND A1.inflow = A2.outflow
AND A2.block_time > A1.block_time
AND A2.block_time < DATE_ADD(A1.block_time, INTERVAL 1 DAY)
AND A1.address_id IN ( ... ) # some candidates
)
and data in the block_time column are of the form:
2020-01-03 14:10:00
so I don't think I need to cast data with CAST() or DATE(). What's wrong with this SQL query?
Part of my Python code
mySQL_user = '''
SELECT address_id
FROM address_history A1
WHERE EXISTS (
SELECT *
FROM address_history A2
WHERE A1.address_id = A2.address_id
AND A1.inflow = A2.outflow
AND A2.block_time > A1.block_time
AND A2.block_time < DATE_ADD(A1.block_time, INTERVAL 1 DAY)
AND A1.address_id IN (
'''
Above code is the skeleton of my query, and I appended some candidates using:
mySQL_user += f"'{address}'"
where address is a string variable. I also separated candidates using ", "(comma), and I added two ")" at the end using:
mySQL_user += "))"
