Python CMA Entry Limit

I am using the Python SDK and I am having trouble with the syntax for increasing the limit of returned entries to 1000 instead of the default 100. My code is below:

content_type = cmaClient.content_types(‘xxxxxxxxxx’, ‘master’).find(‘monograph’)

entries = content_type.entries(limit:‘1000’)

Maybe this will make it works:
entries = content_type.entries({‘limit’: 1000})
