python - Sort a list where there are strings, floats and integers -


is there way in python sort list there strings, floats , integers in it?

i tried use list.sort() method of course did not work.

here example of list sort:

[2.0, true, [2, 3, 4, [3, [3, 4]], 5], "titi", 1]

i sorted value floats , ints, , type: floats , ints first, strings, booleans , lists. use python 2.7 not allowed to...

expected output:

[1, 2.0, "titi", true, [2, 3, 4, [3, [3, 4]], 5]]

python's comparison operators wisely refuse work variables of incompatible types. decide on criterion sorting list, encapsulate in function , pass key option sort(). example, sort repr of each element (a string):

l.sort(key=repr)

to sort type first, contents:

l.sort(key=lambda x: (str(type(x)), x))

the latter has advantage numbers sorted numerically, strings alphabetically, etc. still fail if there 2 sublists cannot compared, must decide do-- extend key function see fit.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
