现在,我们已经有了格式化的文本,我们将其写入文件中。我们使用write()函数将文本写入文件。 file.write(formatted_text) 1. 步骤5: 关闭文件 完成写入操作后,我们需要关闭文件以确保资源的正确释放。 file.close() 1. 完整示例代码 importosfile=open('output.txt','w')name='John Doe'
1. 或者,如果你想将格式化的字符串保存到文件中,你可以使用以下代码: withopen("formatted_text.txt","w")asfile:file.write(formatted_string) 1. 2. 在这个示例中,我们使用了open函数来打开一个名为formatted_text.txt的文件,并使用write方法将格式化的字符串写入文件中。请确保在运行此代码之前,文件夹中不...
