You can use a for loop to loop around the buckets in your S3. In boto3 there is a fucntion that helps this task go easier.(buckets.all())

You can use the following program to print the names of bucket

import boto3
s3 = boto3.resource('s3')
for bucket in s3.buckets.all():
    print (bucket.name)

Hope this helps.

Hi,

If i want to return this listed bucket.information from a function, how could this be done ?

Yes, you can do that I guess. Create one function as given below. It should work.

def fun():
    import boto3
    s3 = boto3.resource('s3')
    for bucket in s3.buckets.all():
        print (bucket.name)
    return bucket.name

Now call the function.

fun()
Suppose i have 10 buckets in my AWS account and i want to list only 5 buckets. How could this be done ?
Hi,

You can create one if-else block and use one counter. If it reaches 5 break your loop.
I mean, not just random 5 buckets out of 10.  I want to list specific 5 buckets out of 10.
Example: There are buckets named: a, b, c, d, e, f, g, h, i,  j...... I want to list a, d, f, h, j out of them.

How could this be achieved ?

You have to create your own customize code according to your use case. I don't think any inbuilt function is available.
