The separator between the arguments to print() function in Python is space by default. 25 but the MSB upper most two bits will be same so one bit can be ignored and the lower 15 bits can be rounded. We will see two Python programs, first program does the conversion using a user defined function and in the second program we are using a in-built function bin() for the decimal to binary conversion. Otherwise, values must be a tuple with exactly the number of items specified by the format string, or a single mapping object.
