Study Notes

Boolean Data Types

  • Comparing values in a program results in a Boolean value: True or False.
  • Boolean values are used to represent truth or falsehood.
  • Comparison Operators:
    • > (greater than)
    • < (less than)
    • >= (greater than or equal to)
    • <= (less than or equal to)
    • == (equal to)
    • != (not equal to)
  • Boolean Variables:
    • A variable that stores a Boolean value (True or False) is called a Boolean variable.
    • Boolean variables can hold either True or False.
    • True and False are reserved words and cannot be used as identifiers.
  • Converting Boolean Values to Integers:
    • Python represents True as 1 and False as 0.
    • The int() function converts a Boolean value to its corresponding integer equivalent.
    • int(True) returns 1.
    • int(False) returns 0.
  • Converting Numeric Values to Boolean Values:
    • The bool() function converts a numeric value to a Boolean value.
    • bool(0) returns False.
    • bool(any other number) returns True.
  • Puzzle:
    • The output of the provided code example:
      • x = 2
      • y = 3
      • r = 5
      • bool(r) = True
      • bool(r - r) = False
    • Calculation steps:
      • x = int(True) + int(True) + int(int(True) - int(True)) ---> x = 1 + 1 + 0 ---> x = 2
      • y = int(True) * int(bool(50) * 3) ---> y = 1 * (1 * 3) ---> y = 3
      • r = x + y ---> r = 2 + 3 ---> r = 5
      • bool(r) ---> bool(5) ---> True
      • bool(r - r) ---> bool(5 - 5) ---> bool(0) ---> False

Generating Random Numbers

  • Generating Random Integers:
    • The randint(a, b) function from the random module generates a random integer between a and b (inclusive).
    • To use the randint() function, you need to import the random module: import random.
    • Example: random.randint(0, 9) generates a random integer from 0 to 9.
  • Program 1: Math Learning Tool:
    • The program demonstrates the use of random numbers to create a math learning tool.
    • It generates two single-digit random numbers and asks the user for the sum.
    • It compares the user's answer to the actual sum and provides feedback.
  • randrange Function:
    • The randrange() function is similar to randint(), but allows for generating integers within a specified range.
    • Example: random.randrange(10) generates a random integer from 0 to 9 (excluding 10).
  • Generating Random Float Numbers:
    • The random() function generates a random float number between 0 and 1 (excluding 1).
    • Example: random.random() returns a random number like 0.56489321458.
  • uniform Function:
    • The uniform(a, b) function generates a float random number within the specified range.
    • Example: random.uniform(1, 10) generates a random number between 1 and 10 (inclusive).
