How do I iterate over the rows in dataframe and swap two adjacent rows and perform some operations on the new dataframe created after the swap?

Question

for i, rows in df.iterrows():
    x, y = df.iloc[rows].copy(), df.iloc[rows+1].copy()
    df.iloc[rows], df.iloc[rows+1] = y, x
    break

I get error on execution:

positional indexers are out-of-bounds`

Answer 1

使用iloc与：

print(df.iloc[[a for b in zip(df.index[::2][::-1],df.index[1::2][::-1]) for a in b]][::-1])
