我有一个函数,要求输入是一个字符串.
我知道我可以断言或检查输入类型,但我想尽可能地处理它.
我有以下代码来处理它.但我想知道是否有任何情况,这一行可以抛出我需要处理的异常.
def foo(any_input):
clean_input = str(any_input) # will this throw any exception or error?
process(clean_input)
尝试str深度嵌套列表时,可能会遇到RuntimeError：
>>> x = []
>>> for i in range(100000):
... x = [x]
...
>>> y = str(x)
Traceback (most recent call last):
File "", line 1, in
RuntimeError: maximum recursion depth exceeded while getting the repr of a list
或者一个MemoryError试图查找一个巨大的列表：
>>> x = 'a'*1000000
>>> y = [x] * 1000000 # x and y only require a few MB of memory
>>> str(y) # but str(y) requires about a TB of memory
Traceback (most recent call last):
File "", line 1, in
MemoryError
