Define the function count_substring(string, substring) that finds how many times the substring appears in the given string.Example:string = "Python is a powerful language. I want to learn Python"substring = "Python"Expected Output:2

To define the function count_substring, follow these steps:

1. Start by defining the function count_substring with two parameters: string and substring.
2. Initialize a variable called count and set it to 0. This variable will keep track of the number of times the substring appears in the string.
3. Use the built-in method count() to count the number of occurrences of the substring in the string. Assign the result to the count variable.
4. Return the value of the count variable as the output of the function.
5. Here is the code implementation:

def count_substring(string, substring):
    count = string.count(substring)
    return count

6. To test the function, you can use the provided example:

string = "Python is a powerful language. I want to learn Python"
substring = "Python"
print(count_substring(string, substring))

This will output: 2, as the substring "Python" appears twice in the given string.
