Python – Add K to Minimum element in Column Tuple List

Python – Add K to Minimum element in Column Tuple List

Let's interpret the task:

Objective: Given a list of tuples, where each tuple represents a column of numbers, add a given number K to the minimum element in each tuple.

Example:

For the list [(5, 3, 8), (2, 7, 9), (10, 1, 3)] and K=5, the result will be: [(5, 8, 8), (7, 7, 9), (10, 6, 3)].

Notice how for each tuple (or column), the minimum number is increased by K.

Here's a step-by-step tutorial:

1. Create a function add_to_min:

This function will accept the list of tuples (column_tuple_list) and the number K to be added to the minimum element of each tuple.

def add_to_min(column_tuple_list, K): # List to store the results result = [] # Iterate over each tuple in the list for column in column_tuple_list: # Find the minimum value in the tuple min_val = min(column) # Create a new tuple where you add K to the minimum value, otherwise keep the number as is new_column = tuple((x + K) if x == min_val else x for x in column) # Append the new tuple to the result list result.append(new_column) return result

2. Test the function:

columns = [(5, 3, 8), (2, 7, 9), (10, 1, 3)] K = 5 print(add_to_min(columns, K)) # Expected: [(5, 8, 8), (7, 7, 9), (10, 6, 3)]

With the add_to_min function, for each tuple in the list, it finds the minimum value. If a number in the tuple matches the minimum value, it adds K to it. Otherwise, it retains the number as is. The modified tuple is then appended to the result list.
