Hi All,
I am getting the user input using the below statment.
Pop_option = arcpy.GetParameterAsText(0)
I am trying to utilise this input value for my business logic.
For this I have treat it as integer. So I have tried to convert this value into integer using below statement.
Pop_option = int(Pop_option) and Pop_option = Pop_option.split(";")

But i am not getting desired datatype.
Can anyone help me on this??

Thanks in advance.

What exaclty is the user entering? Why do you split the string input? What do you mean by "I am not getting the desired datatype" - are you writing the value to a field and that is failing?

If they are just entering a number, i.e.

all you have to do is convert from a string to an integer:

Pop_option_str = arcpy.GetParameterAsText(0)
Pop_option = int(Pop_option_str)

or to be on the safe side:

Pop_option_str = arcpy.GetParameterAsText(0)
try: Pop_option = int(Pop_option_str) # try conversion
except ValueError: arcpy.AddError('Input was not integer...') # input was invalid...

If they are entering something more complex, you will need to provide more information to us before we can help you...

It sounds like you are expecting a multi-value parameter (e.g. '123;234;345').

In this case you can use list comprehensions, the map() function or a loop:

#List comprehension:
Pop_options = [int(p) for p in Pop_option.split(";")]

#Map function
Pop_options = map(int, Pop_option.split(';'))

#Loop
Pop_options=[]
for p in Pop_option.split(';'):
    Pop_options.append(int(p))
