Programming Exercise 4-14
character = ‘#’ # The symbol to print
numRows = 7 # The number of rows
space = ‘ ‘ # The space character
# Iterate over the rows.
for row in range(numRows):
# Each row includes 2 more columns
# than the row number.
for col in range(row + 2):
# Print the symbol in the first
# and last column.
if col == 0 or col == row + 1:
print(character, end=”)
# Add spaces between symbols.
else:
print (space, end=”)
# Go to the next row.
