检查熊猫 df.iterrows() 中的最后一行是否

Question

How can I check last row in Python pandas df.itterows() during its iteration?

My code :

for index, row in df.iterrows():
...     # I want to check last row in df iterrows(). somelike row[0].tail(1)

Answer 1

Use

for i, (index, row) in enumerate(df.iterrows()):
    if i == len(df) - 1:
        pass

Answer 2

The pandas.DataFrame class has a subscriptable index attribute. So one can check the index of the row when iterating over the row using iterrows() against the last value of the df.index attribute like so:

for idx,row in df.iterrows():
    if idx == df.index[-1]:
        print('This row is last')
