Convert string column to int pandas DataFrame

  pandas, python-3.x, replace

I have a Dataframe that has a column with unique string column. like below:

id   customerId               ...
1    vqUkxUDuEmB7gHWQvcYrBn
2    KaLEhwzZxCQ7GjPmVwBVav
3    pybDYgTiCUv3Pv3WLgxKCM
4    zqPiDV33KwrMBZoyeQXMJW
5    CR8z3ThPyzBKXFqqzemQAS
.

I want to replace customerIDs to int by a method like

# replace dataFrame.customerId[from start to end]
dataFrame.customerId.replace(sum(map(ord, ???)))  

How can i do that?
