如果值超过特定字符长度，则从数据集中删除行

import pandas as pd

def remove_rows_by_length(data, column, max_length):
    data = data[data[column].str.len() <= max_length]
    return data

# 示例数据集
data = pd.DataFrame({'Name': ['John', 'Jane', 'Michael', 'Emily'],
                     'Age': [25, 30, 35, 40],
                     'Description': ['This is a short description.', 'This is a long description that exceeds the maximum length.', 'Another short description.', 'Yet another long description that needs to be removed.']})

# 删除Description列中长度超过20的行
max_length = 20
data = remove_rows_by_length(data, 'Description', max_length)
print(data)

    Name  Age                   Description
0   John   25  This is a short description.
2  Michael   35   Another short description.
