TypeError: 'module' object is not callable

[johnescott64]

while running this code:
(
df4
.pipe(PrettyPandas)
.as_currency('USD', subset='Average Value')
.as_percent(subset='Yield')
.total()
.average()
)
I get the error:
TypeError: 'module' object is not callable.

I've successfully pip installed prettypandas
and ran import prettypandas
and import babel

All the documentation uses (PrettyPandas). Is this recognizable in Jupyter Notebooks?
