Chapter 8.3, Problem 16CP

Program Plan Intro

String modification methods:

• • In Python, the method “lower()” would return a copy of a string with its entire letters converted to lowercase.
• • The method “upper()” would return a copy of a string with its entire letters converted to uppercase.

Syntax:

The syntax for “upper()” method is shown below:

  string_variable = ‘string_value’

  string_variable.upper()

Explanation:

In the above syntax,

• • The “string_value” denotes string.
• • The “string_variable” denotes variable that references a string.
• • The “string_variable.upper()” converts the entire string alphabets to upper case characters.
