Write a Python program that prints a square of size depending on an entered

value. The program first reads the size of the square and then prints the square

with a pattern according to the examples below. The figure shows two

different executions of the program.

You should use a pair of nested for$-$loop for printing the pattern and the

program should validate the input to make sure that it is an integer and is larger

than $0,$ prompt an error message for invalid input

Enter size of pattern: $6$

$******$

$*****6$

$****67$

$***678$

$**6789$

$*67890$

Enter size of pattern: $11$

$***********$

$**********1$

$*********12$

$********123$

$*******1234$

$******12345$

$*****123456$

$****1234567$

$***12345678$

$**123456789$

$*1234567890$

Enter size of pattern: a

Size of pattern must be an integer, try again

Enter size of pattern: $-1$

Size of pattern can't be less than or equal to $0,$ try again

Enter size of pattern:
