我想处理AssertionErrors以便向用户隐藏堆栈跟踪的不必要部分，并打印一条消息，说明发生错误的原因以及用户应采取的措施。
有什么方法可以找出assert该except块中失败的行或语句？
try:
assert True
assert 7 == 7
assert 1 == 2
# many more statements like this
except AssertionError:
print 'Houston, we have a problem.'
print
print 'An error occurred on line ???? in statement ???'
exit(1)
我不想将其添加到每个assert语句中：
assert 7 == 7, "7 == 7"
因为它会重复信息。
使用回溯模块：
import sys
import traceback
try:
assert True
assert 7 == 7
assert 1 == 2
# many more statements like this
except AssertionError:
_, _, tb = sys.exc_info()
traceback.print_tb(tb) # Fixed format
tb_info = traceback.extract_tb(tb)
filename, line, func, text = tb_info[-1]
print('An error occurred on line {} in statement {}'.format(line, text))
exit(1)
