How to edit S3 files with python

Question

I am working with python and I need to check and edit the content of some files stored in S3.
I need to check if they have a char o string. In that case, I have to replace this char/string.

For example: I want to replace ; with . in following file File1.txt

This is an example;

After replace

File1.txt

This in an example.

Is there a way to do the replace without downloading the file?

Answer 1

Objects in Amazon S3 are immutable (they cannot be changed).

I recommend that your code does the following:

• Download the file from Amazon S3 to local disk
• Perform edits on the local file
• Upload the file to Amazon S3 with the same Key (filename)
