Program Plan Intro

Accessing characters in string:

• • In Python, there are two techniques for accessing characters present in string.
  • ○ Using “for” loop.
    • ■ Each time the loop operates, variable will refer a copy of character in the string that begins with the first character.
  • ○ Using indexing.
    • ■ The characters can be accessed using index.
    • ■ Each character of a string has an index that specifies the string’s position.
    • ■ Indexing starts at 0 and ends with a count of one less than the total number of characters in a string.
