Numeric intelligence of python (Contd..)

• Try to remember our character

Comparisions

• For comparisions python3 has following operators < > <= >= == !=
• Our python3 does know two kinds of comparisions
  • Normal
  • Chained: Interesting our python3 allows us to chain multiple comparision

Integer Precisions

• Python 3 supports integers of unlimited size

Decimals

• What is value of 0.1+0.1+0.1-0.3 for us its zero but how about python3
• I can solve this and show the result as zero if you use fixed point numbers using Decimal

Some other built-in Numeric Tools (Super powers)

• math
• random

Lets use our python3 to build a number guessing game

• We will tell python3 to remember some number randomly
• Now we will ask user to enter inputs
  • if the value entered by user is less than number remeber give hints to the user

Do you want a play a number guessing game?
Let me memorize a value between 1 to 100. Done
Start guessing
10
You are close, guess little bit higher
90
You are too much far away, guess smaller number
30
Great, you are wonderful at guess, play poker/rummy today

Fun with python3

• We are observing strange behavior from python3
• Is the behavior strange or our understanding of python3 w.r.t lists should be changed, Lets discuss this in our next session
