Python Shots! - Data Types

Python Data Types :

• None
• Numeric
  • int (num = 2)
  • float (num = 2.5)
  • complex (num = 1 + 2j)
  • bool (is_num = True)
• sequence
  • List - [1,2,3]
  • Tuple - (1,2,3)
  • Set - {1,2,3}
  • String - ( str = "aman" )
  • Range - ( range(10) )
• map
  • Dictionary - {"key":"value"}

Description in Brief

1. List

   • [10,20,30]=> to store list of elements
   • mutable/can update value
   • used when you need to update values time to time

2. Tuple

   • (1,34,56,7,89,5) => to store list of elements
   • indexing from 0
   • immutable/ can not update values
   • good and fast while looping through of getting data as it can't be updatable

3. Set

   • {23,56,78,90,54} => to store list of elements
   • no indexing
   • stores unique elements only no repeatation
   • fast for searching as it uses hash table concept

4. Dictionary

   • {"key":"value"} => store elements in key value pairs
   • custom indexing
   • used to deal with complex data like data inside data
