How to Check for the Existence of a Specific Character in a String

The in operator returns True if a specific substring or character exists within a string; otherwise, it returns False.

Copy
text = "Python programming"

result = "programming" in text

print(result)  # True

A substring refers to a specific part of a string within a larger string.

The following example checks if the substring 'Welcome' is included in the string greeting.

Copy
greeting = "Hello, welcome!"

if "welcome" in greeting:
    print("'Welcome' is included in the string.")
else:
    print("'Welcome' is not included in the string.")

The in operator is frequently used in conditions, loops, and other scenarios to check if a specific pattern exists within a string.
