When it is required to filter supersequence strings, a simple list comprehension is used.
Example
Below is a demonstration of the same
my_list = ["Python", "/", "is", "alwaysgreat", "to", "learn"]
print("The list is :")
print(my_list)
substring = "ys"
my_result = [sub for sub in my_list if all(elem in sub for elem in substring)]
print("The resultant string is :")
print(my_result)Output
The list is : ['Python', '/', 'is', 'alwaysgreat', 'to', 'learn'] The resultant string is : ['alwaysgreat']
Explanation
A list is defined and is displayed on the console.
A substring is defined.
The list comprehension is used to iterate through the elements using the ‘all’ clause.
This is assigned to a variable.
This is the output that is displayed on the console.
