如何使pyodbc输出更具可读性/更好？

import pyodbc

# 连接数据库
conn = pyodbc.connect('DRIVER={SQL Server};SERVER=localhost;DATABASE=testdb;UID=username;PWD=password')

# 创建游标
cursor = conn.cursor()

# 执行查询
cursor.execute('SELECT * FROM table')

# 获取所有结果
results = cursor.fetchall()

# 遍历结果并打印
for row in results:
    print(row)

# 关闭连接
cursor.close()
conn.close()

import pyodbc

# 连接数据库
conn = pyodbc.connect('DRIVER={SQL Server};SERVER=localhost;DATABASE=testdb;UID=username;PWD=password')

# 创建游标
cursor = conn.cursor()

# 执行查询
cursor.execute('SELECT * FROM table')

# 获取一行结果
row = cursor.fetchone()

# 循环获取并打印每一行结果
while row:
    print(row)
    row = cursor.fetchone()

# 关闭连接
cursor.close()
conn.close()

import pyodbc
import pandas as pd

# 连接数据库
conn = pyodbc.connect('DRIVER={SQL Server};SERVER=localhost;DATABASE=testdb;UID=username;PWD=password')

# 执行查询并将结果存储在DataFrame中
df = pd.read_sql_query('SELECT * FROM table', conn)

# 打印DataFrame
print(df)

# 关闭连接
conn.close()
