def full_pyramid（行）：

print('\nFull pyramid...\n')




for i in range(rows):



    print(' '*(rows-i-1) + '*'*(2*i+1))

字符串=“”

reversed_string = 字符串[::-1]

result_string = " ".join(string)

对于范围 (0 ,25):

result_string += chr(ord('a')+a)

Answer 1

应该这样做

import string

rows = 26
for i in range(rows):
    row = string.ascii_letters[i]
    for c in range(i-1,-1,-1):
        outside = string.ascii_letters[c]
        row = '%s%s%s' % (outside, row, outside)
    space = ' '*(rows-i)
    row = '%s%s%s' % (space, row, space)
    print(row)

Answer 2

这样就可以了

Python 3.x :

def pyramid(rows):
    s = "abcdefghijklmnopqrstuvwxyz"
    for i in range(rows, 0, -1):
        for j in range(i):
            print(' ', end='')
        for k in range(rows-i):
            print(s[k], end='')
        for m in range(rows-i, -1, -1):
            print(s[m], end='')
        print()

pyramid(15)

Python 2.x :

def pyramid(rows):
    s = "abcdefghijklmnopqrstuvwxyz"
    for i in range(rows, 0, -1):
        for j in range(i):
            print(' '),
        for k in range(rows-i):
            print(s[k]),
        for m in range(rows-i, -1, -1):
            print(s[m]),
        print('')

pyramid(15)
