这是我的代码：

# 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.

points = re.findall('(\(.*?\))', line_to_strip)
print(len(points))
for point in points:
print(point)
file.close()
这是输出：

(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)
我想弄清楚如何标注给定的各个点。例如，我如何让代码只吐出 0.793803，或者只吐出 0.136326 等
附录
所以我最终做的是添加这个
(point1, point2, point3, point4, point5) = points
print (point1)
#print (point2)
#print (point3)
#print (point4)
#print (point5)
这产生了：
(0.793803,0.136326,0,0.5,0)
但是当我再次尝试解析并写了
(x,y,z,w,s) = p
它提出了错误 p 未定义
所以我尝试了 (x,y,z,w,s) = point1
这产生了太多的值而无法解包的错误。
我尝试的另一件事是
for point1 in points
p1x = (x,)
print (p1x)
它刚刚产生了第一个 ( 而不是整个 X 值......
有什么解决办法吗？
附录 PT 2
所以会发生这样的事情：
====init=====
Frames Per Second: 24.0
Source Width: 2048
Source Height: 778
Source Pixel Aspect Ratio: 1
Comp Pixel Aspect Ratio: 1
5
frame: 20
(0.793803,0.136326,0,0.5,0)
x: (, y: y0
x: (, y: y0
x: (, y: y0
x: (, y: y0
x: (, y: y0
当我输入这个
(point1, point2, point3, point4, point5) = points
print (point1)
#print (point2)
#print (point3)
#print (point4)
#print (point5)
for point in points:
x, y, *data = point
print(str.format("x: {0}, y: y{1}", x, y))
file.close()
我不知道它为什么拉 (, from (0.793803,0.136326,0,0.5,0)
我可以告诉你，程序认为如果我把 x, y, z, w, s
我想要 x: '(' y: '0' z: '.' w: '7' s: '9' 我不想要：x: 0.793803 y: 0.136326 z: 0 w: 0.5 s: 0
抱歉所有问题，非常感谢您的帮助
