In Python, you can use the pandas library to delete a column of data. Here is a simple example:

import pandas as pd

# 创建一个DataFrame
data = {'A': [1, 2, 3, 4],
        'B': [5, 6, 7, 8]}

df = pd.DataFrame(data)

# 删除列B
df.drop('B', axis=1, inplace=True)

print(df)

When running the code above, the output result will be:

   A
0  1
1  2
2  3
3  4

In this example, we used the drop method to remove column B. The parameter axis=1 indicates that we are deleting a column of data, and inplace=True means that we are making the modification directly on the original DataFrame.
