Pass in a value into Python Class through command line
- by chrissygormley
Hello, I have got some code to pass in a variable into a script from the command line. The script is:
import sys, os
def function(var):
print var
class function_call(object):
def __init__(self, sysArgs):
try:
self.function = None
self.args = []
self.modulePath = sysArgs[0]
self.moduleDir, tail = os.path.split(self.modulePath)
self.moduleName, ext = os.path.splitext(tail)
__import__(self.moduleName)
self.module = sys.modules[self.moduleName]
if len(sysArgs) > 1:
self.functionName = sysArgs[1]
self.function = self.module.__dict__[self.functionName]
self.args = sysArgs[2:]
except Exception, e:
sys.stderr.write("%s %s\n" % ("PythonCall#__init__", e))
def execute(self):
try:
if self.function:
self.function(*self.args)
except Exception, e:
sys.stderr.write("%s %s\n" % ("PythonCall#execute", e))
if __name__=="__main__":
test = test()
function_call(sys.argv).execute()
This works by entering ./function <function> <arg1 arg2 ....>. The problem is that I want to to select the function I want that is in a class rather than just a function by itself. The code I have tried is the same except that function(var): is in a class. I was hoping for some ideas on how to modify my function_call class to accept this.
Thanks for any help.
