df = pd.DataFrame(data, columns=['ID', '公司代码'])


conn = create_engine(F'mysql+pymysql://root:abc@1234@127.0.0.1:3306/test?charset=utf8')

table_name = 'stu_test'
df.to_sql(table_name, conn, if_exists='append', index=False)

解决方法

import pandas as pd
from sqlalchemy import create_engine

# 创建 DataFrame
data = {'ID': [1], '公司代码': ['阿里']}
df = pd.DataFrame(data, columns=['ID', '公司代码'])

from urllib import parse
password = 'abc@1234'
password = parse.quote_plus(password)
conn = create_engine(F'mysql+pymysql://root:{password}@127.0.0.1:3306/test?charset=utf8')

table_name = 'stu_test'
df.to_sql(table_name, conn, if_exists='append', index=False)
