具体更详细的可以参阅官网https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.drop.html 知道了这些参数,接下来就看一看具体的用法,这里以代码的形式举例说明 df = pd.DataFrame(np.arange(12).reshape(3,4), ... columns=['A', 'B', 'C', 'D']) df A B C D 0 0 1...
So below we create a dataframe object that has rows, 'A', 'B', 'C', and 'D'. We will show how you can permanently delete a row. In the code below, we permanently delete the 'D' row from the dataframe. >>> import pandas as pd >>> from numpy.random import randn >>...
drop("x1", axis = 1) # Apply drop() function print(data_new1) # Print updated DataFrameAs shown in Table 2, the previous Python code has created a new pandas DataFrame with one column less, i.e. the variable x1 has been removed....
