Check String Contains List Element

Write a Python program to check if a given string contains an element that is present in a list.

Visual Presentation:

Python List: Check if a given string contains an element, which is present in a list.

Sample Solution:

Python Code:

# Define a function 'test' that checks if any element in a list is present in a given string.
def test(lst, str1):
    # Use a list comprehension to iterate over each element 'el' in the list 'lst'.
    # For each 'el', check if it is present in the string 'str1'.
    result = [el for el in lst if (el in str1)]
    # Return a boolean indicating whether the 'result' list is not empty (i.e., if any element was found in the string).
    return bool(result)

# Define a string 'str1' and a list 'lst' containing substrings.
str1 = "https://www.w3resource.com/python-exercises/list/"
lst = ['.com', '.edu', '.tv']

# Print a message indicating the original string and list.
print("The original string and list:")
# Print the original string.
print(str1)
# Print the list of substrings.
print(lst)

# Print a message indicating the purpose of the following lines of code.
print("\nCheck if", str1, "contains an element, which is present in the list", lst)
# Call the 'test' function to check if any element from the list 'lst' is present in the string 'str1'.
print(test(lst, str1))

# Define a string 'str1' and a list 'lst' containing substrings.
str1 = "https://www.w3resource.net"
lst = ['.com', '.edu', '.tv']

# Print a message indicating the original string and list.
print("\nThe original string and list: " + str1)
# Print the original string.
print(str1)
# Print the list of substrings.
print(lst)

# Print a message indicating the purpose of the following lines of code.
print("\nCheck if", str1, "contains an element, which is present in the list", lst)
# Call the 'test' function to check if any element from the list 'lst' is present in the string 'str1'.
print(test(lst, str1))

Sample Output:

The original string and list: 
https://www.w3resource.com/python-exercises/list/
['.com', '.edu', '.tv']

Check if https://www.w3resource.com/python-exercises/list/ contains an element, which is present in the list ['.com', '.edu', '.tv']
True

The original string and list: https://www.w3resource.net
https://www.w3resource.net
['.com', '.edu', '.tv']

Check if https://www.w3resource.net contains an element, which is present in the list ['.com', '.edu', '.tv']
False
