    <span class="hljs-keyword">for</span> i <span class="hljs-keyword">in</span> range(rows):
        print(<span class="hljs-string">'*'</span> * (i+<span class="hljs-number">1</span>))
        
half_pyramid(<span class="hljs-number">6</span>)

def half_pyramid(rows):

for i in range(rows):

print('*' * (i+1))

def half_pyramid(rows):

for i in range(rows):

for j in range(i+1):

print("*", end="")
