Using short-circuiting makes code difficult to read. An if statement clearly communicates that the code should only be run if a condition is fulfilled.

Witryna5 kwi 2024 · 3.8: Short-Circuit Evaluation of Logical Expressions. When Python is processing a logical expression such as x >= 2 and (x/y) > 2, it evaluates the expression from left to right. Because of the definition of and, if x is less than 2, the expression x >= 2 is False and so the whole expression is False regardless of whether (x/y) > 2 … WitrynaUsing the element-wise operators (&and ) for short-circuiting may yield unexpected results. Examples In the following statement, it doesn't make sense to evaluate the relation on the right if the divisor, b, is zero. The test on the left is put in to avoid generating a warning under these circumstances: x = (b ~= 0) && (a/b > 18.5)
