Program Plan Intro

Operator “in”:

• • The easiest way to search an item in a list is by means of “in” operator.
• • The “in” operator in Python determines whether the searching item is present in a list.
• • If the searching item is present in the list, then this operator returns a “True” value.
• • If the searching item is not present in the list, then this operator returns a “False” value.

Algorithm:

Algorithm to find whether the name “Ruby” is present in the “names” list is as follows:

• • Create a list of strings that stores names and assigns it to “names”.
• • Then, use the “in” operator along with “if” statement to check whether the name “Ruby” is present in the list “names”.
• • If the name “Ruby” is present in the “names” list, then print the message “Hello Ruby”.
• • If the name “Ruby” is not present in the “names” list, then print the message “No Ruby”.
