Function Definition Include Docstring Describes Function Arguments Returned Value 5 Define Q43896599
Each function definition should include a docstring thatdescribes what the function does, its arguments, and its returnedvalue.
5. Define a Python function unsignedDecimalToBinary that expectsan unsigned decimal integer as an argument and returns thecorresponding string of binary digits. You should assume that thecaller provides a correctly formed integer, so no error handling isnecessary.
9. Using the functions you already have defined, define afunction decimalToTwosComp that expects a signed decimal integer asan argument and returns the corresponding twos-complement string ofbinary digits.
10. Define a function signExtend that expects a twos complementstring of binary digits and the total number of bits as argumentsand returns the corresponding twos complement string of binarydigits, sign-extended to that number of bits.
