New Pandas - 1.00 - January 29, 2020
Is Python the world's most popular language?
pass a URL in place of a file name dfs = pd.read_html(url)
date ranges date_range = pd.date_range(date_from, date_to, freq="D")
if you set indicator parameter of merge() to True pandas adds a column that tells you which dataset the row came from merge with approximate match - the tolerance parameter of merge_asof()
pd.merge_asof(trades, quotes, on="timestamp", by='ticker', tolerance=pd.Timedelta('10ms'), direction='backward')
Merge with indicator is also useful for doing anti-joins:
left.merge(right, how="left", indicator=True, ...)
[lambda df: df._merge == "left_only"]
