Prints row and column headings. Use: print_matrix_char (matrix) Parameters: matrix Returns None. a 2D list of strings (2D list) w Sample testing: Number of rows: 3 Number of columns: 4 0 1 2 3 i 0 C u r 1 Z 2 Y a e MTL Test functions.py: 1 functions.py Submit

Answer 1

#Python Code:-

# Method to print 2d list of string
def print_matrix_char(matrix):
  
# Store Number of rows
row=len(matrix)
  
# Store Number of columns
col=0
  
# Calculate number of columns
for i in range(0,len(matrix)):
for j in matrix[i]:
col+=1
break

print("Number of rows : ",row)
print("Number of columns: ",col)
  
#Print the 2d list in desired format.
print(" ",end=" ")
for i in range(0,col):
print(i,end=" ")
print()
  
for i in range(0,row):
print(i,end=" ")
for j in range(0,col):
print(matrix[i][j],end=" ")
print()
  
def main():
# 2d list of string
matrix=["curi","zycx","eqym"]
# Calling method to print the list.
print_matrix_char(matrix)
  
if __name__=="__main__":
main()
  
  
  

main.py 1 # Method to print 2d list of string 2. def print_matrix_char(matrix): # Store Number of rows row=len(matrix) # Store Number of columns col=0 3 4 5 6 7 8 9 10 11 12 13 14 # Calculate number of columns for i in range(@, len(matrix)): for j in matrix[i]: col+=1 break 15 16 print("Number of rows : ",row) print("Number of columns: ",col) 17 18 19 20 21 #Print the 2d list in desired format. print(" ", end=" ") for i in range(0,col): print(i,end="") print() 22 23 24 26 25 for i in range(0,row): print(i,end=" ") 27 for j in range(0,col): 28 print(matrix[i][j], end=" ") 29 print() 30 31 - def main(): 32 # 2d list of string matrix=["curi","zycx", "eqym" ] 34 # Calling method to print the list. print_matrix_char(matrix) 36 37 if name main 38 main() 33 35
