如何计算SQLITE中表的列数？

PRAGMA table_info(table_name);

import sqlite3

def get_column_count(table_name):
    conn = sqlite3.connect('your_database.db')
    cursor = conn.cursor()
    cursor.execute("PRAGMA table_info({})".format(table_name))
    result = cursor.fetchall()
    column_count = len(result)
    conn.close()
    return column_count

table_name = 'your_table'
column_count = get_column_count(table_name)
print("表 {} 的列数为：{}".format(table_name, column_count))
