1.打开文件 file_object =open('info.txt', mode='rt', encoding='utf-8') 2.读取文件内容,并赋值给datadata= file_object.read() 3.关闭文件 file_object.close() print(data) 读非文本文件 file_object =open('a1.png', mode='rb') data = file_object.read() file_object.close()print(data...
This API creates a folder in an existing bucket to manage data in OBS.OBS does not involve folders like in a file system. All elements stored in OBS buckets are objects.
filename = 'programming.txt' with open(filename, 'w') as file_object: file_object.write("I love programming.") file_object.write("I love create new games.") 附加写入数据 采用w 写入模式在打开文件时会将文件原有数据清空或者覆盖,如果只是希望在文件原有的内容后追加数据,需要使用 a 附加模式打...
