#PYTHON(DAY41)Example Programs

                                        #PYTHON(DAY41)

Example Programs

1) Python Program to Convert Decimal to Binary Using Recursion

# Function to print binary number using recursion
def convertToBinary(n):
   if n > 1:
       convertToBinary(n//2)
   print(n % 2,end = '')

# decimal number
dec = 34

convertToBinary(dec)
print()

And the output is:

100010

2) Python Program to Add Two Matrices

# Program to add two matrices using nested loop

X = [[12,7,3],
    [4 ,5,6],
    [7 ,8,9]]

Y = [[5,8,1],
    [6,7,3],
    [4,5,9]]

result = [[0,0,0],
         [0,0,0],
         [0,0,0]]

# iterate through rows
for i in range(len(X)):
   # iterate through columns
   for j in range(len(X[0])):
       result[i][j] = X[i][j] + Y[i][j]

for r in result:
   print(r)

And the output is:

[17, 15, 4]
[10, 12, 9]
[11, 13, 18]

3) Python Program to Transpose a Matrix

# Program to transpose a matrix using a nested loop

X = [[12,7],
    [4 ,5],
    [3 ,8]]

result = [[0,0,0],
         [0,0,0]]

# iterate through rows
for i in range(len(X)):
   # iterate through columns
   for j in range(len(X[0])):
       result[j][i] = X[i][j]

for r in result:
   print(r)

And the output is:

[12, 4, 3]
[7, 5, 8]
