[SQL] How to pass a parameter into bigquery query on colab

I have a Bigquery query on colab:

from google.colab import auth
auth.authenticate_user()
print('Authenticated')
project_id = '[your project ID]'

sample_count = 2000
df = pd.io.gbq.read_gbq('''
SELECT name, SUM(number) as count
FROM `bigquery-public-data.usa_names.usa_1910_2013`
WHERE state = 'TX'
AND year BETWEEN 1910 AND 1920
GROUP BY name
ORDER BY count DESC
LIMIT 100
''', project_id=project_id, dialect='standard')

df.head()


It works, but now I try to pass a parameter into the query and replace '1920' in the query WHERE clause. this parameter is dependent on another file

end_year = max(record.year) # set end_year

df = pd.io.gbq.read_gbq('''
SELECT name, SUM(number) as count
FROM `bigquery-public-data.usa_names.usa_1910_2013`
WHERE state = 'TX'
AND year BETWEEN 1910 AND end_year
GROUP BY name
ORDER BY count DESC
LIMIT 100
''', project_id=project_id, dialect='standard')

df.head()


But I get an error:

BadRequest: 400 Syntax error: Unexpected identifier "end_year"


I guess the parameter doesn't pass into the query successfully, but I don't know how to fix it.
