This article is about how to create files of any size in python. The editor thinks it is very practical, so I hope you can get something after reading this article. Let's take a look at it with the editor.

There may be application requirements for creating files of any size. To achieve this requirement, you need to open the file in binary mode and offset the file pointer according to the size requirement

Def createfile (filename,size):

With open (filename, 'wb') as f:

F.seek (size-1)

F.write (b'\ x00')

If _ _ name__ = ='_ _ main__':

Createfile ('test.db', 53421)

After opening the file, offset, and then write a byte of content, the last byte must be written, otherwise the file will not be as large as expected. What is the maximum size of a file that can be created? This depends on the number of bits of the operating system and the format of the file system, this part of the content I have not verified, and dare not say nonsense, in the windows 64-bit environment, if the file size exceeds 4G, then the open function can not be opened in a non-binary way, at this time must be opened in a binary way.

The above is how to create files of any size in python. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
