We are given a tuple consisting of only binary values (0 or 1). Using this tuple, we need to convert the tuple into an integer.Input: tup = (1, 0, 1, 1, 0) Output: 22 Method 1:One method to solve the problem is by using the bitwise shift operator to left shift bits of the...
First, it converts the digits to a plain unsigned integer, disregarding the sign bit. Next, it uses two bitmasks to extract the sign and magnitude bits, whose locations depend on the specified bit-length. Finally, it combines them using regular arithmetic, knowing that the value associated ...

I will discuss and show examples of datetime objects in python. Specifically, I will show how to convert a string to a datetime, how to compare and reformat datetime variables, how to work with timezones, and how to extract specific bits of information. You can see heretypes of objects in...
