Python Pandas遍历行并访问列名

我也喜欢

itertuples()

for row in df.itertuples():    print(row.A)    print(row.Index)

由于行是一个名为元组，如果你打算访问值在每行，这应该是 MUCH 快

速度运行：

df = pd.Dataframe([x for x in range(1000*1000)], columns=['A'])st=time.time()for index, row in df.iterrows():    row.Aprint(time.time()-st)45.05799984931946st=time.time()for row in df.itertuples():    row.Aprint(time.time() - st)0.48400020599365234
