A dictionary is something like an array that s accessed by keys  e g  strings      rather than just plain sequential numbers  It contains key value pairs  you can look up values using a key like using a phone book  key name  number value   For defining such a dictionary  you use this syntax using curly braces  see also  http   wiki python org moin SimplePrograms

Dictionaries in Python are data structures that store key-value pairs  You can use them like associative arrays  Curly braces are used when declaring dictionaries   d     One   1   Two    2   Three    3   print d  Two     prints  2    Curly braces are not used to denote control levels in Python  Instead  Python uses indentation for this purpose   I think you really need some good resources for learning Python in general  See https   stackoverflow com q 175001 10077
