Slicing of arrays is done with [first:last+1].
One trick I tend to use a lot of is to indicate extra information with ellipses. So, if your field is one hundred characters, I would use:
if len(s) <= 100:
print s
else:

Losing scope when using ng-include
...meCtrl scope:
To store what the user typed into HomeCtrl's $scope.lines array, I suggest you pass the value to the addLine function:
<form ng-submit="addLine(lineText)">
In addition, since lineText is owned by the ngInclude scope/partial, I feel it should be responsible for clearing it:...

Javascript - removing undefined fields from an object [duplicate]
...
This solution also avoids hasOwnProperty() as Object.keys returns an array of a given object's own enumerable properties.
Object.keys(obj).forEach(function (key) {
if(typeof obj[key] === 'undefined'){
delete obj[key];
}
});
and you can add this as null or '' for stricter cleaning.
