When it is required to trim tuples based on a K value, a simple iteration and the ‘append’ method is used.
Below is a demonstration of the same −
Example
my_list = [(44, 3, 68, 11, 5), (68, 44, 9, 5, 8), (8, 11, 2, 68, 5), (44, 68, 2, 5, 7)]
print("The list is :")
print(my_list)
K = 1
print("The value for K is ")
print(K)
my_result = []
for element in my_list:
list_length = len(element)
my_result.append(tuple(list(element)[K: list_length - K]))
print("The resultant list is :")
print(my_result)Output
The list is : [(44, 3, 68, 11, 5), (68, 44, 9, 5, 8), (8, 11, 2, 68, 5), (44, 68, 2, 5, 7)] The value for K is 1 The resultant list is : [(3, 68, 11), (44, 9, 5), (11, 2, 68), (68, 2, 5)]
Explanation
A list of tuple is defined and is displayed on the console.
The value for K is defined and is displayed on the console.
An empty list is defined.
The list is iterated over and the length of every element is stored in a variable.
The elements from K to difference between length of list and K are accessed using indexing, and converted to a tuple.
This is appended to the empty list.
This is displayed as output on the console.
