您正在用
df['a'] != 'stop'
过滤出停止行。 这是一个替代代码:# df['stop_loc'] = ( (df['a'] == 'stop') | (df['a'] == 'wildcard') ).cumsum() df['stop_loc'] = df['a'].isin(['stop', 'wildcard']).cumsum() def zip_entries(x): return list(x.a)[0], list(zip(x.a[1:], x.b[1:])) df_new = (df[(df['stop_loc'] != df['stop_loc'].max())] .groupby('stop_loc') .apply(zip_entries) .apply(pd.Series)) print(df_new) # 0 1 # stop_loc # 1 stop [(a1, 2), (a1, 3)] # 2 stop [(a2, 5)]
You are filtering out the stop rows with
df['a'] != 'stop'
. Here is an alternative code:# df['stop_loc'] = ( (df['a'] == 'stop') | (df['a'] == 'wildcard') ).cumsum() df['stop_loc'] = df['a'].isin(['stop', 'wildcard']).cumsum() def zip_entries(x): return list(x.a)[0], list(zip(x.a[1:], x.b[1:])) df_new = (df[(df['stop_loc'] != df['stop_loc'].max())] .groupby('stop_loc') .apply(zip_entries) .apply(pd.Series)) print(df_new) # 0 1 # stop_loc # 1 stop [(a1, 2), (a1, 3)] # 2 stop [(a2, 5)]
