Python:检查变量类型 [英] Python: checking type of variables

问题描述

我对python有疑问.

I have a question about python.

我有变量a，b，c和d.

我有以下一行:

if    not isinstance(a, int)   or not isinstance(b, int)  \
   or not isinstance(c, int)   or not isinstance(d, int)  \
   or not isinstance(a, float) or not isinstance(b, float)\
   or not isinstance(c, float) or not isinstance(d, float):
    do something

是否可以使这段代码更短?

Is it possible to make this code shorter?

谢谢！

推荐答案

U应该使用all:

if not all(isinstance(var, (int, float)) for var in [a, b, c, d]):
    # do stuff

请注意，您可以在isinstance调用中同时提供int和'float'.

Note, that you can supply both int and 'float' to the isinstance call.
