Question

The following task does not involve writing program code: instead, you will be writing function signatures for hypothetical functions (you will be defining functions in subsequent tasks).

1. For this task, you are presented with several 'hypothetical' functions. These aren't built-in Python functions: they are functions that you will have to define (i.e. implement, write) yourself later. however, you only need to write a signature for each hypothetical function listed here:
   1. toThePower(): takes two numbers e.g. x and y , and returns the value of (x to the power y). For example, toThePower(3,3) returns 27, and toThePower(-0.1,3) returns -0.001.
   2. quadruplicate(): takes a string, and returns a string consisting of three copies of that string concatenated together. For example, quadruplicate("na") returns "nananana", and quadruplicate("..?") returns "..?..?..?..?".
   3. subtract(): takes two numbers, and returns the difference between them. For example, subtract(10,3) returns 7, and subtract(2.2,5) returns -2.8.
   4. overlap(): We are not going to tell you exactly what it does, but we will give you a few examples: overlap("banana","analyze") returns 3 (not 4), overlap("abracadabra","abraham") returns 4 (not 5), overlap("foobar","red") returns 1, and overlap("foobar","bazinga") returns 0.
   5. multiplicate(): We are not going to tell you exactly what it does, but we will give you a few examples: multiplicate("x",5) returns "xxxxx", multiplicate("goo",3) returns "googoogoo", and multiplicate("never",0) returns "" (the empty string).

Answer 1

def toThePower(x,y):
return x**y;
  
def quadruplicate(string):
return string*4;
  
def subtract(x,y):
return x-y;
  
def multiplicate(string,times):
return string*times;
  

  
print(toThePower(-0.1,3))
print(quadruplicate("na"))
print(subtract(10,3))
print(multiplicate("goo",3))
