为什么“和”条件在我的 Python 代码中不起作用？

Question

Each separate statement is true, but why is the combination of the two with "and" false? codes

Answer 1

In python and is a logical AND that returns True if both the operands are true whereas '&' is a bitwise operator. I think you are trying to to something like this.

if (other_list[0] == 0 and rand_vec[0] == 1):
    # Do something

Answer 2

Many thanks to Pw Wolf and all others. Now I understand it.

Original code:

if (other_list[0] == 0 & rand_vec[0] == 1):

    # do something 

Improved code:

if (other_list[0] == 0 and rand_vec[0] == 1):

    # do something
