lesen X, Y, Z aus der Datei, Tupel/Liste String ohne Anführungszeichen durch Liste gefolgt ändern

Question

Ziel:

Python verwenden, erhalten FreeCAD.Vector(223.90,67.99,45.00) aus TXT-Datei.

Comma getrennte Textdateiformat:

1.0,8.2,9.888 
6.345,4.32,2.43 
... 

d.h. X, Y, Z als Schwimmer. Eine spezifische Anwendung "FreeCAD" Python verwendet als Basisskriptsprache (Makros) Die native Methode zu einem nativen FreeCAD Objekt ist VectorFreeCAD.Vector d.h. der Vektor (X, Y, Z), d.h. FreeCAD.Vector(105453.164062,90917.8671875,1274.77026367).

Als weiteres ausführliches Beispiel:

>>> points=[FreeCAD.Vector(-2.50563430786,0.3603053689,0.0),FreeCAD.Vector(-1.67500686646,0.959897279739,0.0),FreeCAD.Vector(-0.53083139658,0.393310427666,0.0),FreeCAD.Vector(0.767367601395,0.932393193245,0.0)] 
>>> line = Draft.makeWire(points,closed=False,face=True,support=None) 
>>> Draft.autogroup(line) 

Hier ist ein Beispiel für die data.txt Datei:

105507.460938 91080.125 1331.37109375 
105509.648438 91077.9375 1326.85534668 
105501.375 91072.890625 1318.00634766 
105487.0 91070.3984375 1318.89746094 

Hinweis: Das Trennzeichen kann Komma oder Leerzeichen sein - es ist nicht wichtig und kann entweder

Das Problem:

eine Variable erstellen, die diesen Wert hat:

[FreeCAD.Vector(-2.50563430786,0.3603053689,0.0),FreeCAD.Vector(-1.67500686646,0.959897279739,0.0),...

oder

Erarbeitung einen Weg, um die Eingabe zu montieren, so dass die FreeCAD die XYZ-Eingang akzeptieren kann.

Im Allgemeinen ist die Frage, wie eine solche Hybrid-String-Liste zu machen, ist mir schwer zu fassen.

ich in diesem Stadium bin oder Arbeits durch Ausgabe:

## Open the file with read only permit 
# f = open('C:/Users/Greg/Desktop/txt/pipe_example_s.txt', "r") 

## use readlines to read all lines in the file 
## The variable "lines" is a list containing all lines 
#lines = f.read().splitlines() 


with open('C:/Users/Greg/Desktop/txt/pipe_example_c.txt') as f: 
    mylist = [tuple(map(float, i.split(','))) for i in f] 

## close the file after reading the lines. 
#f.close() 
print mylist 
print "One" 
print mylist[0] 

p1 = 34.8999 
print "FreeCAD.Vector (%s)" % '34.8999, 2.8997, 3.09665' 

p1 = "FreeCAD.Vector (%s)" % '34.8999, 2.8997, 3.09665' 
print p1 

p2 = 123.456 
p1 = "FreeCAD.Vector (%s)" % (p2) + '34.8999, 2.8997, 3.09665' 
print p1 


p3 = tuple(mylist) 
print p3 

s = '(0.0034596999, 0.0034775001, 0.0010091923)' 
s = s.replace(',', 'FreeCAD.Vector ') 
print(s) # -> [0.0034596999 0.0034775001 0.0010091923]

Answer 1

Es ist nicht ganz klar, was Sie mit Hilfe benötigen, aber vielleicht wird diese geben Ihnen einige Ideen, die Ihnen helfen könnten, das Problem zu lösen:

>>> def vector(x, y, z): 
...  print("vector: x=%f, y=%f, z=%f" % (x, y, z)) 
... 
>>> vector(1, 2, 3) 
vector: x=1.000000, y=2.000000, z=3.000000 
>>> v = [1, 2, 3] 
>>> vector(*v) 
vector: x=1.000000, y=2.000000, z=3.000000
