Python: Find the strings in a list containing a given substring
Find Strings with Substring
Write a Python program to find strings in a given list containing a given substring.
Input: [(ca,('cat', 'car', 'fear', 'center'))] Output: ['cat', 'car'] Input: [(o,('cat', 'dog', 'shatter', 'donut', 'at', 'todo', ''))] Output: ['dog', 'donut', 'todo'] Input: [(oe,('cat', 'dog', 'shatter', 'donut', 'at', 'todo', ''))] Output: []

Sample Solution:
Python Code:
# Define a function named 'test' that takes a list of strings 'strs' and a substring 'substr' as input
def test(strs, substr):
# Use a list comprehension to filter strings in 'strs' that contain the given 'substr'
return [s for s in strs if substr in s]
# Create a list of strings 'strs' with specific elements
strs = ['cat', 'car', 'fear', 'center']
# Print the original list of strings
print("Original strings:")
print(strs)
# Assign a specific substring 'substrs' to the variable
substrs = 'ca'
# Print the substring
print("Substring: " + substrs)
# Print a message indicating the operation to be performed on the list
print("Strings in the said list containing a given substring:")
# Print the result of the test function applied to the 'strs' list with the given substring
print(test(strs, substrs))
# Create a different list of strings 'strs' with specific elements
strs = ['cat', 'dog', 'shatter', 'donut', 'at', 'todo', '']
# Print the original list of strings
print("\nOriginal strings:")
print(strs)
# Assign a different substring 'substrs' to the variable
substrs = 'o'
# Print the substring
print("Substring: " + substrs)
# Print a message indicating the operation to be performed on the list
print("Strings in the said list containing a given substring:")
# Print the result of the test function applied to the modified 'strs' list with the updated substring
print(test(strs, substrs))
# Create another list of strings 'strs' with specific elements
strs = ['cat', 'dog', 'shatter', 'donut', 'at', 'todo', '']
# Print the original list of strings
print("\nOriginal strings:")
print(strs)
# Assign a different substring 'substrs' to the variable
substrs = 'oe'
# Print the substring
print("Substring: " + substrs)
# Print a message indicating the operation to be performed on the list
print("Strings in the said list containing a given substring:")
# Print the result of the test function applied to the modified 'strs' list with the updated substring
print(test(strs, substrs))
Sample Output:
Original strings: ['cat', 'car', 'fear', 'center'] Substring: ca Strings in the said list containing a given substring: ['cat', 'car'] Original strings: ['cat', 'dog', 'shatter', 'donut', 'at', 'todo', ''] Substring: o Strings in the said list containing a given substring: ['dog', 'donut', 'todo'] Original strings: ['cat', 'dog', 'shatter', 'donut', 'at', 'todo', ''] Substring: oe Strings in the said list containing a given substring: []
