Python: Find the elements of a given list of strings that contain specific substring using lambda
Python Lambda: Exercise-39 with Solution
Write a Python program to find the elements of a given list of strings that contain a specific substring using lambda.
Sample Solution:
Python Code :
# Define a function 'find_substring' that filters elements containing a substring in a list
def find_substring(str1, sub_str):
# Use the 'filter' function with a lambda to filter elements in 'str1' containing 'sub_str'
result = list(filter(lambda x: sub_str in x, str1))
# Return the filtered list
return result
# Create a list 'colors' containing strings representing different colors
colors = ["red", "black", "white", "green", "orange"]
# Print the original list 'colors'
print("Original list:")
print(colors)
# Set a substring 'sub_str' to search within the list 'colors' and print it
sub_str = "ack"
print("\nSubstring to search:")
print(sub_str)
# Print elements from 'colors' that contain the specific substring using the 'find_substring' function
print("Elements of the said list that contain the specific substring:")
print(find_substring(colors, sub_str))
# Change the substring 'sub_str' to search and print it
sub_str = "abc"
print("\nSubstring to search:")
print(sub_str)
# Print elements from 'colors' that contain the new specific substring using 'find_substring' function
print("Elements of the said list that contain the specific substring:")
print(find_substring(colors, sub_str))
Sample Output:
Original list: ['red', 'black', 'white', 'green', 'orange'] Substring to search: ack Elements of the said list that contain specific substring: ['black'] Substring to search: abc Elements of the said list that contain specific substring: []
