Initializing the Maya Environment in and for Python

Initializing the Maya Environment in and for Python

Maya runs any Python commands in the userSetup.py file whenever it starts up. You can use this file to set up your working environment or execute commonly used Python commands such as importing the maya.cmds module.

The userSetup.py script is executed during the initialization and setup phase of Maya; therefore, only commands which set up your working environment and have no dependencies on Maya functionality can be successfully run in this script.

NoteYou can use maya.utils.executeDeferred() to delay code execution until after the Maya scene is initialized. For more information, see maya.utils.
  1. Create a file named userSetup.py in the following folder:
    • Windows: <drive>:\Documents and Settings\<username>\My Documents\maya\<Version>\scripts
    • Mac OS X: ~/Library/Preferences/Autodesk/maya/<version>/scripts
    • Linux: ~/maya/<version>/scripts
  2. In the userSetup.py file, type the commands you want Maya to run on start up; for example, import maya.cmds as mc.
    NoteMake sure you save the file with the right extension (.py).

Python2.5 中 由cloneNode(xml.dom.minidom)产生的xml Node元素的tagName问题

Python2.5 中

由cloneNode(xml.dom.minidom)产生的xml Node元素的tagName

与 最开始的原始节点建立时的tagName相同，

不管你中间的克隆节点的tagName改变成什么,

也不管原始节点的tagName改变成什么!

 

下面是测试代码：

  1. #!/usr/bin/env python
  2. #coding:UTF-8
  3. from xml.dom import minidom
  4.  
  5. xmlStr = '<?xml version="1.0" encoding="UTF-8"?><test><oldTagName/></test>'
  6. xmlDoc = minidom.parseString(xmlStr)
  7. firstNode = xmlDoc.firstChild
  8.  
  9. originalNode = firstNode.firstChild
  10. originalNode.setAttribute('name','originalNode')
  11. print 'This is original Node.'
  12. print originalNode.toxml()
  13. print '-------------------------------------------'
  14.  
  15. originalNode.tagName = 'original_Changed'
  16. print 'I give the originalNode a new tagName.'
  17. print originalNode.toxml()
  18. print '-------------------------------------------'
  19.  
  20. cloneNode = originalNode.cloneNode(0)
  21. cloneNode.setAttribute('name','cloneNode')
  22. print 'This is clone Node from original Node, The tagName is the same as the old tagName of original Node!!!.'
  23. print cloneNode.toxml()
  24. print '-------------------------------------------'
  25.  
  26. cloneNode.tagName = 'isChanged'
  27. print 'I give cloneNode a new tagName.'
  28. print cloneNode.toxml()
  29. print '-------------------------------------------'
  30.  
  31. cloneCloneNode = cloneNode.cloneNode(0)
  32. cloneCloneNode.setAttribute('name','cloneCloneNode')
  33. print 'This is clone Node from colne Node, The tagName is the same as the old tagName of original Node!!!.'
  34. print cloneCloneNode.toxml()
  35. print '-------------------------------------------'
  36.  
  37. cloneCloneNode.tagName = 'isChanged_too'
  38. print 'I give the cloneCloneNode a new tagName.'
  39. print cloneCloneNode.toxml()
  40. print '-------------------------------------------'
  41.  
  42. originalNode.tagName = 'flow_Changed'
  43. print 'I give the originalNode a new tagName.'
  44. print originalNode.toxml()
  45. print '-------------------------------------------'
  46.  
  47. CCCNode = cloneCloneNode.cloneNode(0)
  48. cloneNode.setAttribute('name','CCCNode')
  49. print 'This is clone Node from cloneCloneNode, The tagName is the same as the old tagName of original Node!!!.'
  50. print CCCNode.toxml()
  51. print '-------------------------------------------'
  52.  
  53. NewCloneNode = originalNode.cloneNode(0)
  54. NewCloneNode.setAttribute('name','NewCloneNode')
  55. print 'This is noe clone Node from originalNode, The tagName is the same as the old tagName of original Node!!!.'
  56. print NewCloneNode.toxml()
  57. print '-------------------------------------------'
  58.  
  59. print 'so, The tagName of the clone clone Node == The the old tagName  of original Node!!!!!!!!!!'
  60. print 'The attributes of the clone clone Node == The attributes of the clone Node'

 

结果：

This is original Node.
<oldTagName name="originalNode"/>
-------------------------------------------
I give the originalNode a new tagName.
<original_Changed name="originalNode"/>
-------------------------------------------
This is clone Node from original Node, The tagName is the same as the old tagName of original Node!!!.
<oldTagName name="cloneNode"/>
-------------------------------------------
I give cloneNode a new tagName.
<isChanged name="cloneNode"/>
-------------------------------------------
This is clone Node from colne Node, The tagName is the same as the old tagName of original Node!!!.
<oldTagName name="cloneCloneNode"/>
-------------------------------------------
I give the cloneCloneNode a new tagName.
<isChanged_too name="cloneCloneNode"/>
-------------------------------------------
I give the originalNode a new tagName.
<flow_Changed name="originalNode"/>
-------------------------------------------
This is clone Node from cloneCloneNode, The tagName is the same as the old tagName of original Node!!!.
<oldTagName name="cloneCloneNode"/>
-------------------------------------------
This is noe clone Node from originalNode, The tagName is the same as the old tagName of original Node!!!.
<oldTagName name="NewCloneNode"/>
-------------------------------------------
so, The tagName of the clone clone Node == The the old tagName  of original Node!!!!!!!!!!
The attributes of the clone clone Node == The attributes of the clone Node
