如何通过Python在CSV中保存文件，保持小数点分隔符不变？(以及Excel和Google工作表之间的差异)

import csv

def save_csv(data, filename):
    with open(filename, 'w', newline='', encoding='utf-8') as f:
        writer = csv.writer(f)
        writer.writerows(data)

data = [
    ['姓名', '年龄', '成绩'],
    ['张三', 18, 95.5],
    ['李四', 20, 88.9],
    ['王五', 19, 92.3]
]

save_csv(data, 'data.csv')

pip install pandas

import pandas as pd

def save_excel(data, filename):
    df = pd.DataFrame(data)
    df.to_excel(filename, index=False)

data = [
    ['姓名', '年龄', '成绩'],
    ['张三', 18, 95.5],
    ['李四', 20, 88.9],
    ['王五', 19, 92.3]
]

save_excel(data, 'data.xlsx')
