我已经用C编写了这个练习，在那里我能够在printf(%2i)和printf(%3i)的帮助下输出格式良好的表。在

在Python中，如何在数字前面添加空格以使其看起来更好？在#! python3

# 007.py - Write a program that prints a multiplication table for numbers up to 12.

print('----------------------------------------')

print('Multiplication Table from 1 - 12')

print('----------------------------------------')

print(' 1 2 3 4 5 6 7 8 9 10 11 12')

print('----------------------------------------')

for i in range(1, 13):

if i > 1:

print('\n', end="")

print(' ' + str(i) + ' |', end="")

result = i

for n in range(1, 13):

result = i * n

print(' ' + str(result), end="")

print('\n')

print('----------------------------------------')

输出：

^{pr2}$
