设置pandas数据框中的列宽

import pandas as pd

# 设置列宽度为80个字符
pd.set_option('display.max_colwidth', 80)

# 创建数据框
data = {'Name': ['John', 'Alice', 'Bob'],
        'Age': [25, 30, 35],
        'City': ['New York', 'Paris', 'London'],
        'Description': ['This is a long description that exceeds the default column width.',
                        'Another long description that needs to be displayed properly.',
                        'Short description.']}
df = pd.DataFrame(data)

# 打印数据框
print(df)
