Python’s eval () allows you to evaluate arbitrary Python expressions from a string-based or compiled-code-based input. This function can be handy when you’re trying to dynamically evaluate Python expressions from any input that comes as a string or a compiled code object.
15 lip 2024 · Linear equations using one variable of the form a + bx = c + dx can be solved in Python using eval() function. The input type will be a linear equation in the form of a string. Syntax: eval(expression, globals=None, locals=None) Here, we will transform the equation into an expression of real and imaginary numbers such that eval can easily process i
Learn what is eval() function in Python with examples. See globals and locals parameters and vulnerabilities in using Python eval() function.
