>================== run tutorial inside of spyder with adjusted sys.path =====================

running in spyter, the toga_2.py gets its own interpreter, start fresh each time

added code for sys.path ( does not run without this, some may have more than absolutely necessary )

print( "--- modify sys.path if necessary add until it works ---" ) import sys for_sys_path    = [] for_sys_path.append( "/home/russ/python03" ) for_sys_path.append( "/home/russ/toga/src" ) for_sys_path.append( "/home/russ/toga/src/core" ) for_sys_path.append( "/home/russ/toga/src/gtk" ) for_sys_path.append( '/home/russ/anaconda3/lib/python3.6/site-packages' ) test_path_add = for_sys_path [0]

if sys.path[ 0 ] != test_path_add: print( "adding to sys.path" ) sys.path  = for_sys_path + sys.path pass else: print( " sys.path already modified" )

similiar failure in straight ahead python ..... -

- no output shown

- also works in ipython from terminal if path setting is changed to: ---

print( " sys.path set from literal" ) sys.path = ['/home/russ/python03', '/home/russ/toga/src', '/home/russ/toga/src/core', '/home/russ/toga/src/gtk', '/home/russ/anaconda3/lib/python3.6/site-packages', '', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/russ/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', '/usr/lib/python3/dist-packages/IPython/extensions', '/home/russ/.ipython']
 * 1) brute force
