Question

I don't know which one is wrong. Can you please check.

Thank you

QUESTION 1

1. In the following code, how many and which functions have been defined/declared?

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		1 function: powerNum
   		1 function: powerNum
   		3 functions: powerNum, and main is defined/declared twice.
   		2 functions: powerNum and main

QUESTION 2

1. In the following code, which of the variable(s) is (are) considered as global variable(s):

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		p and power
   		pNum
   		p
   		power
   		n

QUESTION 3

1. In the following code, which line of code is returning the value for function powerNum?

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		def powerNum(power):
   		print ("Power of the number you entered is", powerNum (p))
   		return pNum
   		pNum = n ** power

QUESTION 4

1. In the following code, which of the variable(s) is (are) considered as parameter variable(s):

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		n
   		pNum
   		p and power
   		p
   		power

QUESTION 5

1. After learning about the issues with global variables, Amita took the old code with global variables in cell A and re-wrote without global variables. Based on the partial code done in the cell below, what changes, if any, need to be made to the code in cell-B below?

   cell-A: Old code with global variables	cell-B: Partial new code without global variables
   def powerNum(power): pNum = n ** power return pNum n = int(input("Enter a number whose power you want to calculate: ")) def main(): p = int(input("Enter the power number: ")) print ("Power of the number you entered is", powerNum (p)) main()	def powerNum(power): pNum = n ** power return pNum def main(): n = int(input("Enter a number whose power you want to calculate: ")) p = int(input("Enter the power number: ")) print ("Power of the number you entered is", powerNum (p)) main()

   		We need to just change powerNum function to accept two parameters: one for power value and one for the number as below def powerNum(power, n):
   		No changes need to be made to main or powerNum functions
   		Yes, powerNum should now be defined with two parameters: one for power value and one for the number as below def powerNum(power, n): Also we will need to change how the function is called in main function as below: powerNum(p,n)
   		We need to just pass the additional argument when the powerNum function is called in main function as below: powerNum(p,n)

QUESTION 6

1. In the following code, which line of code is calling or invoking function powerNum?

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		return pNum
   		def powerNum(power):
   		pNum = n ** power
   		print ("Power of the number you entered is", powerNum (p))

QUESTION 7

1. In the following code, which line of code is defining or declaring function powerNum?

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		def powerNum(power):
   		return pNum
   		pNum = n ** power
   		print ("Power of the number you entered is", powerNum (p))

QUESTION 8

1. In the following code, which of the variable(s) is(are) considered as argument(s):

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		p and power
   		n
   		power
   		p
   		pNum

QUESTION 9

1. In python, how can you pass arguments to a function?

   		by keyword arguments only and can be in any order
   		default is by position but you can also pass by keyword arguments as in the case below: show_interest (rate=0.01, periods=10, principal=10000.0)
   		by position only and they must be passed in the same order in which they are defined in the function header
   		by position only and they can be passed in any order irrespective of how are they are defined

QUESTION 10

1. In the following code, in which order do the lines of code get executed?

   def powerNum(power):

   pNum = n ** power

   return pNum

   n = int(input("Enter a number whose power you want to calculate: "))

   def main():

   p = int(input("Enter the power number: "))

   print ("Power of the number you entered is", powerNum (p))

   main()

   		getting input n from the user >>  calling main function >> calling powerNum function >> ending in powerNum function
   		calling powerNum function >>  getting input n from the user >>  calling main function
   		getting input n from the user >> calling main function >> calling powerNum function >> returning back to main function from powerNum function

Answer 1

Answer 1:-

In this question 2 function were defined/declaired, one is 'main' and other one is 'powerNum', so correct option is,

2 functions: powerNum and main

Answer 2:-

Variable 'n' doesn't belong to any function scope, it is defined outside any function. Hence it is global variable, so correct option is,

n

Answer 3:-

"return pNum" statement is returning value from "powerNum" function

Answer 4:-

Variables present in function signature is called function parameters, so correct option is,

power

Answer 5:-

Since there is no local variable with name 'n', so there won't be any issue, correct option is,

No changes need to be made to main or powerNum functions

Answer 6:-

Function call contains function names followed by paranthesis, so correct option is,

print ("Power of the number you entered is", powerNum (p))

Answer 7:-

Function declairation/defination starts with "def" keyword, so correct option is,

def powerNum(power)

Answer 8:-

Variables that are written inside the paranthesis during function call are called function arguments, correct option is,

p

Answer 9:-

default is by position but you can also pass by keyword arguments as in the case below:

show_interest (rate=0.01, periods=10, principal=10000.0)

Answer 10:-

getting input n from the user >> calling main function >> calling powerNum function >> returning back to main function from powerNum function
