Code description

game_schedule.py

# cording:uft-8
import pandas as pd
yyyy = 2020
url = 'https://data.j-league.or.jp/SFMS01/search?'
category = {'1': 477, '2': 478, '3': 479}
schedule = pd.DataFrame(index=None, columns=['year', 'Tournament', 'section', 'Match day', 'K/O time', 'home', 'Score', 'Away', 'Stadium', 'Number of visitors', 'Internet broadcasting / TV broadcasting'])

Create J1, J2, J3 categories and yearly IDs in dic format. Create an empty data frame.

game_schedule.py

for key, value in category.items():
    para = 'competition_years=' + str(yyyy)
    para1 = '&competition_frame_ids=' + str(key)
    para2 = '&competition_ids=' + str(value)
    para3 = '&tv_relay_station_name='

    full_url = url + para + para1 + para2 + para3
    # print(full_url)
    df = pd.read_html(full_url, attrs={'class': 'table-base00 search-table'}, skiprows=0)
    schedule = pd.concat([schedule, df[0]], sort=False)

The point is pd.read_html (full_url, attrs = {'class':'table-base00 search-table'} ..., which specifies the target URL and the attributes of <table>. Combine the retrieved ones into the schedule.

game_schedule.py

#If you want to replace NaN
# schedule = schedule.fillna({'KO time': '● Undecided ●', 'Visitors':0})
schedule.to_csv('./csv/Game_Schedule_' + str(yyyy) + '.csv', index=False, sep=',')

Save in csv format in the specified folder.
