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 specific substring using lambda.

Sample Solution:

Python Code :

def find_substring(str1, sub_str):
    result = list(filter(lambda x: sub_str in x, str1))
    return result
colors = ["red", "black", "white", "green", "orange"]
print("Original list:")
print(colors)

sub_str ="ack"
print("\nSubstring to search:")
print(sub_str)
print("Elements of the said list that contain specific substring:")
print(find_substring(colors, sub_str))
sub_str ="abc"
print("\nSubstring to search:")
print(sub_str)
print("Elements of the said list that contain 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:
[]

Python: Tips of the Day

Use Enumerate() In for Loops:

>>> students = ('John', 'Mary',  'Mike')
>>> for i, student in enumerate(students):
  ...     print(f'Iteration:  {i}, Student: {student}')
  ... 
Iteration: 0, Student: John
Iteration: 1, Student: Mary
Iteration: 2, Student: Mike
>>> for i, student in enumerate(students,  35001):
  ...      print(f'Student Name: {student}, Student ID #: {i}')
  ... 
Student Name: John, Student ID #: 35001
Student Name: Mary, Student ID #: 35002
Student Name: Mike, Student ID #: 35003
