Formatting Output
- 2. CONSTANTS
- 3. DATA TYPE CONVERSION • Can control how variables are interpreted within the program: • Two types: • Evaluation • Code: eval(string) • Ex. eval(“51” + “52”) • eval( str1 ** str2) • test = eval(input(“Enter a num”)) • Conversion • Code: datatype(value/variable) • Ex. int(4.5) 4 • float(4) 4.0 • str(num) “4”
- 4. THE ESCAPE SEQUENCE • Used within a string to perform a specific task • Code: print(“”This is an example”n”)
- 5. FORMATTING OUTPUT • Controls how the information is displayed: • size • Position • Justification • padding • number of digits • Dataytype • The format function formats a number, string, or both and returns the information as a string. • Code: format(variable, ‘format-specifier’)
- 6. THE FORMAT FUNCTION Code: print(format(item, ‘ ’)
- 7. THE FORMAT FUNCTION Code: print(format(item, ‘ ’)
