Fastest way to insert these dashes in python string?

Question

So I know Python strings are immutable, but I have a string:

c[\'date\'] = \"20110104\"

Which I would like to convert to

c[\'da         


        

Answer 1

I am not sure if you want to convert it to a proper datetime object or rather just hard code the format, you can do the following:

from datetime import datetime
result = datetime.strptime(c['date'], '%Y%m%d')
print result.date().isoformat()

Input: '20110104'

Output: '2011-01-04'
