假设我有以下数据帧,并希望按ys分组:
xs ys 0 0 0 1 1 0 2 2 1 3 3 1
我可以通过跑步来做到这一点
grouped = df.groupby('ys')
我可以很好地遍历这个新的groupby对象,但我想要一个group
在以下循环中访问的数据帧列表:
for name, group in grouped: do_something(group)
这可能吗?
当然,只是迭代群体!
>>> import pandas as pd, numpy as np >>> df = pd.DataFrame(dict(xs=list(range(4)), ys=[0,0,1,1])) >>> df xs ys 0 0 0 1 1 0 2 2 1 3 3 1 >>> grouped = df.groupby('ys') >>> dataframes = [group for _, group in grouped] >>> dataframes [ xs ys 0 0 0 1 1 0, xs ys 2 2 1 3 3 1] >>>
