Here's what it looks like in boto3(tested with version 1.2.3).

First, create a presigned url with s3.generate_presigned_url method:

>>> import boto3
>>> s3 = boto3.client('s3')
>>> s3.generate_presigned_url('put_object', Params={'Bucket':'YourBucket', 'Key':'YourKey'}, ExpiresIn=3600, HttpMethod='PUT')
u'https://s3-ap-northeast-1.amazonaws.com/YourBucket/YourKey?AWSAccessKeyId=AKIAXXXXXXXXXXXXXXXX&Expires=1451061671&Signature=%2FtyAyCd5vrp13p%2FqLdoPkox7yTM%3D'

PUT to S3 with a presigned URL

$ curl \
  --request PUT \
  --upload-file path/to/file \
  "https://s3-ap-northeast-1.amazonaws.com/YourBucket/YourKey?AWSAccessKeyId=AKIAXXXXXXXXXXXXXXXX&Expires=1451061671&Signature=%2FtyAyCd5vrp13p%2FqLdoPkox7yTM%3D"
