Question

I am working with Ruby every day, but i have an issue in Python. I was found this languages very similar… But I have some problems with migration from Ruby 🙂

Please, help me to convert this action in python:

   string = "qwerty2012"
   (var, some_var, another_var)  = string.unpack("a1a4a*")

this should return three variables with unpacked values from string:

   var         = "q"      # a1
   some_var    = "wert"   # a4
   another_var = "y2012"  # a*

Help me to represent it in Python
Thank you!

Answer 1

s = "qwerty2012"
var, some_var, another_var = s[:1], s[1:5], s[5:]

will do the assignment and yield respectively:

q
wert
y2012

The above assignment makes use of slice notation as described by the Python Docs. This SO post Good Primer for Python Slice Notation gives a good explanation too.
