You can use that function to do a binary search in Python in the following way: Python import math def find_index(elements, value): left, right = 0, len(elements) - 1 while left <= right: middle = (left + right) // 2 if math.isclose(elements[middle], value): return middle if...
Once the file is opened with the appropriate mode, Python provides several methods to write data into the file. The write() method directly inserts text or information into the file, while the print() function, augmented with the file parameter, streamlines the process by redirecting the ...
