Question

Using Python Programming Language:

4. Implement the following function in the PyDev module functions.py and test it from a PyDev module named t04.py: def print_matrix_char(matrix): Prints the contents of a 2D list of strings in a formatted table. Prints row and column headings. Use: print_matrix_char (matrix) Parameters: matrix - a 2D list of strings (2D list) Returns: None. Sample testing: Number of rows: 3 Number of columns: 4 0 1 2 3 i 0 с u r 1 с у q 2 e у m

Answer 1

Below is the python solution with output screenshot

Note : I have also commented the code for better understanding

Code :

def print_matrix_char(matrix):
    # print the number of rows and column
    print("Number of rows:", len(matrix))
    print("Number of columns:", len(matrix[0]))
    # print the new line 
    print()
    print("\t", end="")
    # first print the upper line for columns
    for i in range(len(matrix[0])):
        print(i,end="\t")
    print()
    # print the matrix
    for i in range(len(matrix)):
        # print the row number
        print(i,end="\t")
        for j in range(len(matrix[0])):
            print(matrix[i][j],end = "\t")
        print()

if __name__ == "__main__":
    matrix = [['c', 'u', 'r', 'i'],
              ['z', 'y', 'c', 'x'],
              ['e', 'q', 'y', 'm']]
    print_matrix_char(matrix)

Note : for better formatting please refer to the code screenshot below

Output :
