文件的写入

1、使用write方法将数据写入到文件中

with open('test.txt', 'w') as file:
    file.write('我爱Python！')

2、使用writelines方法将多个数据写入到文件中

with open('test.txt', 'w') as file:
    file.writelines(['我爱Python！', '我爱Python！'])

3、指定编码将数据写入文件（默认使用系统编码）

with open('test.txt', 'w', encoding='utf-8') as file:
    file.write('我爱Python！')
