Question

Implement the following functions in a module called arrayfunctions.py. You must use the booksite modules stdarray and stdio to implement the functions.  

print1Darray() takes a one dimensional integer array argument and prints it (field width for each element should be 5).

print2Darray() takes a two dimensional integer array argument and prints it (field width for each element should be 5 - should be printed as a m x n matrix).

add2Darrays() takes 2, two dimensional integer array arguments. You can assume the arrays are the exact same size. The function returns a new array that is the addition of the 2 arrays passed in.  

print2DarrayBoolean() takes a two dimensional boolean array argument and prints a * in place of True and a space in place of False. Include row and column numbers.  

Answer 1

Codes for above methods in Python3 are as follows:

def print1Darray(arr):
   for value in arr:
       print("%-5d" % value,end='')
   print("")
  
def print2Darray(arr):
   for row in arr:
       print1Darray(row)
      
def add2Darrays(a,b):
   add=[]
   for i in range(len(a)):
       temp=[]
       for j in range(len(a[0])):
           temp.append(a[i][j]+b[i][j])
       add.append(temp)
   return add
  
def print2DarrayBoolean(arr):
   for row in arr:
       for col in row:
           if(col):
               print("*",end='')
           else:
               print(" ",end='')
       print("")

print1Darray([1,2,3,4,5])
print("")
print2Darray([[1,2,3],[4,5,6]])
print("")
print2Darray(add2Darrays([[1,2,3],[4,5,6]],[[1,2,3],[4,5,6]]))
print("")
print2DarrayBoolean([[True,False,True],[True,False,True]])
