The example of get_metadata in the wiki has two errors

Here is the link: https://github.com/blackducksoftware/hub-rest-api-python/wiki/Client-API-Reference#get_resource

Example

for project in bd.get_resource('projects'):
    m = get_metadata('versions', project)
    print("Num versions: " + m['totalCount'])

is a shortcut for:

for project in bd.get_resource('projects'):
    m = get_resource('versions', project, items=False, params={'limit': 1})
    print("Num versions: " + m['totalCount'])

Error1: Without bd, get_metadata error found

Traceback (most recent call last):
  File "get_resource.py", line 43, in <module>
    m = get_metadata('versions', project)
NameError: name 'get_metadata' is not defined

Error2: Another error is that can not concatenate str to int

Traceback (most recent call last):
  File "get_resource.py", line 44, in <module>
    print("Num versions: " + m['totalCount'])
TypeError: can only concatenate str (not "int") to str

The above code could be modified as follows: (tested and run without error)

for project in bd.get_resource('projects'):
    m = bd.get_metadata('versions', project)
    print(f"Num versions: {m['totalCount']}")

is a shortcut for:

for project in bd.get_resource('projects'):
    m = bd.get_resource('versions', project, items=False, params={'limit': 1})
    print(f"Num versions: {m['totalCount']}")
