如何缩进以下打印件

Question

假设我有其他人的功能，它执行以下操作：

def print_numbers(N):
    for i in range(N):
        print(i,'- something something')

现在不改变函数我想从外部调用它，这样它就会以初始缩进方式打印（为了简单起见，我们可以说\t）：

Here are some random numbers:
     0 - something something
     1 - something something
     2 - something something
     3 - something something
     4 - something something

我尝试过这样的事情：

print('Here are some random numbers:')
with textwrap.set_indent('\t'):
    print_numbers(5)

但是我找不到这样的方法.. 有可能吗？

你可以这样做：

def print_numbers(N):
    for i in range(N):
        print(i,'- something something')

def special_print(*args):
    pf('\t', *args)

pf = print # save reference to original built-in
print = special_print # override
print_numbers(5)
print = pf # reset built-in
