Python: Find the strings in a list containing a given substring
Python Programming Puzzles: Exercise-16 with Solution
Write a Python program find the 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:
def test(strs, substr):
return [s for s in strs if substr in s]
strs = ['cat', 'car', 'fear', 'center']
print("Original strings:")
print(strs)
substrs = 'ca'
print("Substring: "+substrs)
print("Strings in the said list containing a given substring:")
print(test(strs, substrs))
strs = ['cat', 'dog', 'shatter', 'donut', 'at', 'todo', '']
print("\nOriginal strings:")
print(strs)
substrs = 'o'
print("Substring: "+substrs)
print("Strings in the said list containing a given substring:")
print(test(strs, substrs))
strs = ['cat', 'dog', 'shatter', 'donut', 'at', 'todo', '']
print("\nOriginal strings:")
print(strs)
substrs = 'oe'
print("Substring: "+substrs)
print("Strings in the said list containing a given 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: []

Clamps num within the inclusive range specified by the boundary values x and y:
Example:
def tips_clamp_num(num,x,y): return max(min(num, max(x, y)), min(x, y)) print(tips_clamp_num(2, 4, 6)) print(tips_clamp_num(1, -1, -6))
Output:
4 -1
