Rooted by: Print a square of characters
Fork Selected
  • Description

    print a square of numbers but in a string rather then a list.

    improvement ideas, add a second parameter to choose whether the output should be a list or string.

     Code 
    def square(n):
    print(("*" *n+"\n")*n) # to see the result
    
    return (("*" *n+"\n")*n)[:-1]
    Test Cases 
    # TODO: Given a number, write a function that prints a square with the caracter '*'
# These are some of the methods available:
#   test.expect(boolean, [optional] message)
#   test.assert_equals(actual, expected, [optional] message)
#   test.assert_not_equals(actual, expected, [optional] message)

# You can use Test.describe and Test.it to write BDD style test groupings


# test.assert_equals(square(2),['**', '**'])
# test.assert_equals(square(3),['***', '***', '***'])
# test.assert_equals(square(4),['****', '****', '****', '****'])
# test.assert_equals(square(5),['*****', '*****', '*****', '*****', '*****'])

test.assert_equals(square(2),"**\n**")
test.assert_equals(square(5),'*****\n*****\n*****\n*****\n*****')
test.assert_equals(square(4),'****\n****\n****\n****')
