Python: Check the nth-1 string is a proper substring of nth string of a given list of strings
Python Programming Puzzles: Exercise-5 with Solution
Write a Python program to check the nth-1 string is a proper substring of nth string in a given list of strings.
Input: ['a', 'abb', 'sfs', 'oo', 'de', 'sfde'] Output: True Input: ['a', 'abb', 'sfs', 'oo', 'ee', 'sfde'] Output: False Input: ['a', 'abb', 'sad', 'ooaaesdfe', 'sfsdfde', 'sfsd', 'sfsdf', 'qwrew'] Output: False Input: ['a', 'abb', 'sad', 'ooaaesdfe', 'sfsdfde', 'sfsd', 'sfsdf', 'qwsfsdfrew'] Output: True

def test(str1):
return str1[len(str1)-2] in str1[len(str1)-1] and str1[len(str1)-2] != str1[len(str1)-1]
str11 = ["a","abb","sfs", "oo", "de", "sfde"]
print("Original list:")
print(str11)
print("Check the nth-1 string is a proper substring of nth string of the said list of strings:")
print(test(str11))
str11 = ["a","abb","sfs", "oo", "ee", "sfde"]
print("\nOriginal list:")
print(str11)
print("Check the nth-1 string is a proper substring of nth string of the said list of strings:")
print(test(str11))
str11 = ["a","abb","sad", "ooaa" "esdfe", "sfsdfde", "sfsd", "sfsdf", "qwrew"]
print("\nOriginal list:")
print(str11)
print("Check the nth-1 string is a proper substring of nth string of the said list of strings:")
print(test(str11))
str11 = ["a","abb","sad", "ooaa" "esdfe", "sfsdfde", "sfsd", "sfsdf", "qwsfsdfrew"]
print("\nOriginal list:")
print(str11)
print("Check the nth-1 string is a proper substring of nth string of the said list of strings:")
print(test(str11))
Sample Output:
Original list: ['a', 'abb', 'sfs', 'oo', 'de', 'sfde'] Check the nth-1 string is a proper substring of nth string of the said list of strings: True Original list: ['a', 'abb', 'sfs', 'oo', 'ee', 'sfde'] Check the nth-1 string is a proper substring of nth string of the said list of strings: False Original list: ['a', 'abb', 'sad', 'ooaaesdfe', 'sfsdfde', 'sfsd', 'sfsdf', 'qwrew'] Check the nth-1 string is a proper substring of nth string of the said list of strings: False Original list: ['a', 'abb', 'sad', 'ooaaesdfe', 'sfsdfde', 'sfsd', 'sfsdf', 'qwsfsdfrew'] Check the nth-1 string is a proper substring of nth string of the said list of strings: True

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
