Python assert(断言)可以分别后面的判断是否正确,如果错误会报错
作用:后面的程序需要依赖前面的条件(可以用if、else代替)
示例:
a = 1
assert type(a) is int
print('No problem')
输出结果:
No problem
a = ''
assert type(a) is int
print('No problem')
输出结果:
Traceback (most recent call last):
File "D:/test.py", line 3, in <module>
assert type(a) is int
AssertionError
