Turning off Feature Classes in ArcGIS Pro using ArcPy?

Question

I'm struggling to create a python script that will simply turn off all feature classes in the table of contents within my ArcGIS Pro project. I think part of my problem is the syntax change from ArcMap to Pro. I know that ESRI has a web page dedicated to that very issue (http://pro.arcgis.com/en/pro-app/arcpy/mapping/migratingfrom10xarcpymapping.htm), but the diagram on that page just seems to confuse me more.

Here is my attempt at creating a script to to turn off feature classes in ArcGIS Pro.

import arcpy
p = arcpy.mp.ArcGISProject("Current")
for lyrx in arcpy.mp.ListLayers(p):
    print lyrx.name('')
    lyrx.visible = False

When I run the code above I receive the following message

File "<string>", line 4
  print lyrx.name('')
         ^
SyntaxError: invalid syntax

ArcGIS Pro uses Python 3.x, as such, the print command is a function. It requires you to use it like a function print(lyrx.name) where as in Python 2 you could get away with doing print lyrx.name

Note I've removed the ('')....I'm not sure what you're doing what that bit of code.

edit in regards to your comment: The arcpy "mapping" syntax between ArcMap and Pro has changed in regards to arcpy "mp". You'll want to read the help, specifically the map and layer class.

aprx = arcpy.mp.ArcGISProject(r"C:\path\to\aprx.aprx")
m = aprx.listMaps("name of your map")[0] #0= first map it finds that matches that name
lyrList = m.listLayers()
for lyr in lyrList:
   lyr.visible = False
