Итак, у меня есть код, который выдает выходные данные, и мне нужно извлечь информацию между запятыми, назначить их переменной, которая динамически изменяется при вызове ... вот мой код:
import re
data_directory = 'Z:/Blender_Roto/'
data_file = 'diving_board.shape4ae'
fullpath = data_directory + data_file
print("====init=====")
file = open(fullpath)
for line in file:
current_line = line
# massive room for optimized code here.
# this assumes the last element of the line containing the words
# "Units Per Second" is the number we are looking for.
# this is a non float number, generally.
if current_line.find("Units Per Second") != -1:
fps = line_split = float(current_line.split()[-1])
print("Frames Per Second:", fps)
# source dimensions
if current_line.find("Source Width") != -1:
source_width = line_split = int(current_line.split()[-1])
print("Source Width:", source_width)
if current_line.find("Source Height") != -1:
source_height = line_split = int(current_line.split()[-1])
print("Source Height:", source_height)
# aspect ratios
if current_line.find("Source Pixel Aspect Ratio") != -1:
source_px_aspect = line_split = int(current_line.split()[-1])
print("Source Pixel Aspect Ratio:", source_px_aspect)
if current_line.find("Comp Pixel Aspect Ratio") != -1:
comp_aspect = line_split = int(current_line.split()[-1])
print("Comp Pixel Aspect Ratio:", comp_aspect)
# assumption, ae file can contain multiple mocha shapes.
# without knowing the exact format i will limit the script
# to deal with one mocha shape being animated N frames.
# this gathers the shape details, and frame number but does not
# include error checking yet.
if current_line.find("XSpline") != -1:
# record the frame number.
frame = re.search("\s*(\d*)\s*XSpline", current_line)
if frame.group(1) != None:
frame = frame.group(1)
print("frame:", frame)
# pick part the part of the line that deals with geometry
match = re.search("XSpline\((.+)\)\n", current_line)
line_to_strip = match.group(1)
points = re.findall('(\(.*?\))', line_to_strip)
print(len(points))
for point in points:
print(point)
print("="*40)
file.close()
Это дает мне вывод:
====init=====
Frames Per Second: 24.0
Source Width: 2048
Source Height: 778
Source Pixel Aspect Ratio: 1
Comp Pixel Aspect Ratio: 1
frame: 20

(0.793803,0.136326,0,0.5,0)
(0.772345,0.642332,0,0.5,0)
(0.6436,0.597615,0,0.5,0)
(0.70082,0.143387,0,0.5,0.25)
(0.70082,0.112791,0,0.5,0)
========================================
Так что мне нужно, например, иметь возможность назначить (0.793803, 0.136326, 0, 0.5, 0) для (1x, 1y,1z, 1w, 1s), (0,772345,0,642332,0,0,5,0) до (2x, 2y, 2z, 2w, 2s) и т. Д., Чтобы независимо от того, какие числа занимают эти позиции, они займут это значение.
вот код, в который мне нужно поместить эти числа:

x, y, z = cList[num]
polyline.points[num].co = (x, y, z, w)
MakePolyLine("NameOfMyCurveObject", "NameOfMyCurve", listOfVectors)
Итак, где у меня есть мой вектор, я бы хотел разместить его (px, py, 0.z, pw,ps) затем (p2.x, p2.y, p2.zp2.wp2.s) и т. д., чтобы она могла меняться в зависимости от заданного числа
Любая помощь будет отличной .. Заранее спасибо!
