如何import 一個py 到目前跑的py上

在動態執行的情況下，由「變數」(指定一個filename)，來import~
一般來說，是已知path及filename，做import path.filename(without py)
但這個就有點點小複雜…

def importPythonFileAsModule(strModulePathName):
    ImportModule = None
    # Check File exist
    if ( False == checkIsFile(strModulePathName) ):
        print "Python File: %s doesn't exist!\n" % (strModulePathName)
        return ImportModule

    # Saving current working directory
    CWD = os.getcwd()

    # Split pathname & filename
    (strModule_path , strModule_name) = os.path.split(strModulePathName)

    # Get module name from filename
    #strModule_name = str(strModule_name).lower()
    if ( strModule_name[-3:] == ".py" ):
        strModule_name = strModule_name[:-3]

    # Change to module's path
    os.chdir(strModule_path)

    # Import Module
    try:
        ImportModule = __import__(strModule_name)
    except:
        print "Import Module: %s in %s failed!\n" % (strModule_name, strModule_path)

    # Back to Original Path
    os.chdir(CWD)

    return ImportModule

1. 先把filename做split 成 path 及file 兩段
2. change working directory 到path
3. import它，return 接一個 objectname

即可~~~


至於Perl的部份：
****先留一個指令「Do」…
下次再來研究~~~趕工優先~~~

修正版，利用sys.path ，python在讀module時的預設path來方便我做import…

def importPythonFileAsModule(strModulePathName):
    ImportModule = None
    # Check File exist
    if ( False == os.path.isfile(strModulePathName) ):
        print "Python File: %s doesn't exist!\n" % (strModulePathName)
        return ImportModule

    # Saving current working directory
    CWD = os.getcwd()

    # Split pathname & filename
    (strModule_path , strModule_name) = os.path.split(strModulePathName)

    # Get module name from filename
    #strModule_name = str(strModule_name).lower()
    if ( strModule_name[-3:] == ".py" ):
        strModule_name = strModule_name[:-3]

    # Change to module's path
    os.chdir(strModule_path)

    # Import Module
    try:
        sys.path.append(strModule_path)
        ImportModule = __import__(strModule_name)
        sys.path.pop()
    except:
        print "Import Module: %s in %s failed!\n" % (strModule_name, strModule_path)

    # Back to Original Path
    os.chdir(CWD)

    return ImportModule

其實只加了兩行：
sys.path.append(strModule_path)
ImportModule = __import__(strModule_name)
sys.path.pop()

就是加入path、import完、再拿掉~~~
