python - 如何连接以下数据框

Question

我有两个数据框：

file_date = str((date.today() - timedelta(days = 2)).strftime('%m-%d-%Y'))
file_date

github_dir_path = ' https://github.com/CSSEGISandData/COVID-19/raw/master/csse_covid_19_data/csse_covid_19_daily_reports/ ' file_path = github_dir_path + file_date + '.csv' 第一个数据帧：

请指导我如何连接两个数据框。我尝试了几件事，但没有得到预期的结果。
