Difference between assert and raise in Python
In this article you will learn once and for all the difference between assert and raise in Python, and also their applications in code.
Hey you programmer, ok? Let’s learn more about assert and raise in the Python language!
Let’s talk about the raise first, this operator is used to call an Exception somewhere in the code
The exception will be invoked when the raise is executed, see this example:
x = 1 if(x == 1): raise Exception("X variable should not be 1")
When the conditional is computed as true, code execution will stop because of the Exception that raise broke out
Now let’s see the assert, in this statement a code expression is evaluated
If true, the code continues to run normally, but if false, an Exception is invoked.
See a practical example:
x = 1 assert x == 2, "x must be 2"
Exception with assert is called AssertionError
And Which One Should We Choose?
We have two different approaches here, the assert in turn depends on a True or False to work
It will always check for such an operation to be performed
The raise can be executed at any time, not depending exclusively on a condition
In this article we learned the difference between assert and raise in Python
The assert statement will always depend on a conditional to invoke an exception
In the case of a raise, we can call an Exception whenever it is relevant
