This document discusses various Python concepts related to variables, data types, formatting output, and the format function. It explains that eval() can control how variables are interpreted, datatype() can convert values to different data types, escape sequences are used within strings to perform tasks, and format() formats a number or string according to a format specifier and returns a string.

1. FORMATTING
VARIABLES AND
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, ‘ ’)
