# Python Exercise: Generates a two-dimensional array

## Python Conditional: Exercise-11 with Solution

Write a Python program that takes two digits m (row) and n (column) as input and generates a two-dimensional array. The element value in the i-th row and j-th column of the array should be i*j.

Note :

i = 0,1.., m-1

j = 0,1, n-1.

**Pictorial Presentation:**

**Sample Solution:**

**Python Code :**

```
# Prompt the user to input the number of rows
row_num = int(input("Input number of rows: "))
# Prompt the user to input the number of columns
col_num = int(input("Input number of columns: "))
# Create a 2D list (a list of lists) filled with zeros using list comprehension
# The outer list will have 'row_num' elements and the inner lists will have 'col_num' elements
multi_list = [[0 for col in range(col_num)] for row in range(row_num)]
# Nested loop to populate the 2D list with multiplication results
for row in range(row_num):
for col in range(col_num):
# Set the value at position [row][col] in the 2D list to the product of 'row' and 'col'
multi_list[row][col] = row * col
# Print the resulting 2D list containing the multiplication table
print(multi_list)
```

Sample Output:

Input number of rows: 3 Input number of columns: 4 [[0, 0, 0, 0], [0, 1, 2, 3], [0, 2, 4, 6]]

**Previous:** Write a Python program which iterates the integers from 1 to 50. For multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".

**Next:** Write a Python program that accepts a sequence of lines (blank line to terminate) as input and prints the lines as output (all characters in lower case).
