Programming Fundamentals/Variable Examples Python

Overview The following examples demonstrate data types, arithmetic operations, and input in Python. Data Types # This program demonstrates variables, literal constants, and data types. i = 1234567890 f = 1.23456789012345 s = "string" b = True print("Integer i =", i) print("Float f =", f) print("String s =", s) print("Boolean b =", b) Output Integer i = 1234567890 Float f = 1.23456789012345 String s = string Boolean b = true Discussion Each code element represents: # begins a comment i = , d = , s =, b = assign literal values to the corresponding variables print() calls the print function Arithmetic # This program demonstrates arithmetic operations. a = 3 b = 2 print("a =", a) print("b =", b) print("a + b =", (a + b)) print("a - b =", (a - b)) print("a * b =", a * b) print("a / b =", a / b) print("a % b =", (a % b)) Output a = 3 b = 2 a + b = 5 a - b = 1 a * b = 6 a / b = 1.5 a % b = 1 Discussion Each new code element represents: +, -, *, /, and % represent addition, subtraction, multiplication, division, and modulus, respectively. Temperature # This program converts an input Fahrenheit temperature to Celsius. print("Enter Fahrenheit temperature:") fahrenheit = float(input()) celsius = (fahrenheit - 32) * 5 / 9 print(str(fahrenheit) + "° Fahrenheit is " + str(celsius) + "° Celsius") Output Enter Fahrenheit temperature: 100 100.0° Fahrenheit is 37.77777777777778° Celsius Discussion Each new code element represents: input() reads the next line from standard input float() converts the input to a floating-point value References Wikiversity: Computer Programming
