Python Collection Part - 4 [Range,Set,FrozenSet]

For Professionals and Freshers

 

range:

range datatype represents a sequence of values, range datatype is immutable. We can use range in various ways /forms

form1 :  range (10) : it represents value from  0 to 9

form2:   range(10,50): it represents from 10 to 49

form3:  range(10,50,5): it represents 10 to 49 step of 5

range only applicable on integer not on float values.

Set:

If you want to represent a group of object as a single entity where duplication not allowed and insertion order not preserved  then we should go for set

{} - Set can be represented by using curly barcket

s[1:] - indexing order sequencing not applicable on set

s=set()  // way to create empty set
for i in range(10)
s.add(i)

Example2:
s={'govind','ravi','shiva'}


 FrozenSet:
Frozenset is immutable we cant change once created.only one diffrence between set and frozenset is
frozen set is immutable where as set is mmutable

s={10,20,30,40} 
fs=frozenset(s)
type(fs)
