Python programming language supports regular expression. RegEx is a sequence of characters for matching with other strings.

Here, we are given an expression and key. And we have a program to check whether the key is present in the expression.

Let's take an example to illustrate the working of our solution,

Input:
key = "includehelp" ; expression = "learn programming at includehelp"

Output:
True

We will use the in method which checks for the presence of a substring in the string and returns a boolean value based on the comparison.
