如何使用Python 打印各种三角形


						直角三角形







rows = int(input('输入列数：'))

for i in range(1, rows):

print('*' * i)

for i in range(1, rows):

for j in range(i):

print("*", end="")

print("")



等腰直角三角形







rows = int(input('输入列数：'))

for i in range(1, rows):

print(' * ' * i)

for i in range(1, rows):

for j in range(1, i + 1):

print(" * ", end="")

print("")



打印等腰三角形







rows = int(input('输入列数：'))

for i in range(1, rows):

if i % 2 != 0:

str = ('*' * i)

print(str.center(9, ' '))



正方形1







rows = int(input('输入列数：'))

for i in range(0, rows):

print(" * " * rows)

for i in range(0, rows):

for j in range(0, rows):

print(" * ", end="")

print(" ")



正方形2





print('正方形2')

for i in range(10):

for j in range(0, 10 - i):

print(end=' ')

for n in range(0, 0 + i):

print(end=' ')

for m in range(0 + i, 10):

print('', end=' ')

for k in range(10 - i, 10):

print('', end=' ')

print('')



打印倒立直角三角形







for x in range(10):

for i in range(x, 10):

print('*', end='')

print('')



同一行打印直角三角形





print('同一行打印直角三角形')

for j in range(10):

for x in range(0, j):

print('', end='')

for n in range(j, 19 - j):

print(' ', end='')

for k in range(0, j):

print('', end='')

print('')



直角三角形拼装心形





print('直角三角形拼装心形')

for j in range(8):

for x in range(0, j):

print('', end='')

for n in range(j, 19 - j):

print(' ', end='')

for k in range(0, j):

print('', end='')

print('')

for i in range(10):

for j in range(0, 0 + i):

print(end=' ')

for k in range(0 + i, 10):

print('*', end=' ')

print('')



打印倒立等腰三角形1





print('打印倒立等腰三角形1')

for j in range(10):

for x in range(0, j):

print(end=' ')

for n in range(j, 15 - j):

print('*', end='')



打印倒立等腰三角形2





print('打印倒立等腰三角形2')

for i in range(10):

for j in range(0, 0 + i):

print(end=' ')

for k in range(0 + i, 10):

print('*', end=' ')

print('')



同一行打印两个等腰三角形





print('同一行打印两个等腰三角形')

for i in range(10):

for j in range(0, 10 - i):

print(end=' ')

for k in range(10 - i, 10):

print('', end=' ')

for n in range(0, 0):

print(end=' ')

for m in range(0 + i, 10):

print(' ', end=' ')

for jj in range(10, 10):

print(end=' ')

for kk in range(10 - i, 10):

print('', end=' ')

print('')



等腰三角形拼装心形





print('等腰三角形拼装心形')

for i in range(10):

for j in range(0, 10 - i):

print(end=' ')

for k in range(10 - i, 10):

print('', end=' ')

for n in range(0, 0):

print(end=' ')

for m in range(0 + i, 10):

print(' ', end=' ')

for jj in range(10, 10):

print(end=' ')

for kk in range(10 - i, 10):

print('', end=' ')

print('')

for i in range(20):

for j in range(0, 0 + i):

print(end=' ')

for k in range(0 + i, 20):

print('*', end=' ')

print('')
