Question

I am not able to connect to a bucket if the bucket name has a Upper case letter. I have several buckets those has capital letter in it.

>>> mybucket = conn.get_bucket('Vig_import')
Traceback (most recent call last):

Answer 1

S3 recommend that you only use DNS-compliant bucket names.

Take a look at the restrictions page: http://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html

However you do it, in boto you can use a different calling format for buckets with a mixed-case name:

from boto.s3.connection import OrdinaryCallingFormat

conn = boto.connect_s3(calling_format=OrdinaryCallingFormat())
mybucket = conn.get_bucket('Vig_import')

Answer 2

To addings those lines to .boto file are worked for me

[s3]
calling_format = boto.s3.connection.OrdinaryCallingFormat
