Ibuava,
The result of this operation will be a string. Numeric values do not have "dots" in them. Within python, as a string, you can use a simple string slice and append function, such as:
oldNum = str(1234567890)
newNum = oldNum[:2] + "." + oldNum[2:4] + "." + oldNum[4:7] +"." + oldNum[7:]
newNum
'12.34.567.890'
This assumes the oldNum is 10 characters in each entry.
If it is not always10 characters, work from the end of the string value to the front, instead.
If you are trying to do something else, please provide more information so you can get a targeted response to your question.
Regards,
Jim
thanks for your response, that is exactly what i need but i have big date over 20K, i need to do this for all of them. Will this function work for all of them?
Yes, it should not be an issue.
NOTE: You should create a new field and calculate it based off of the original, so if there are any problems, you still have access to the original source field and values.
