To evaluate a string-based expression, Python’s eval() runs the following steps: Parse expression; Compile it to bytecode; Evaluate it as a Python expression; Return the result of the evaluation; The name expression for the first argument to eval() highlights that the function works only with expressions and not with compound statements.
What does it mean to evaluate an algebraic expression? An algebraic expression like 2 x + 3 can be evaluated by substituting a value for x . For example, if x = 4 then: 2 x + 3 = 2 ⋅ 4 + 3 = 8 + 3 = 11. We can also evaluate more complicated expressions that have more than one variable.
To evaluate the expression means to substitute the variable (s) of a polynomial with given value (s). For example, If x=6, x = 6, what is the value of 6x+1? 6x + 1? Substitute 6 6 for x x and follow the order of operations: \begin {aligned} & 6 (6)+1 \\\\ & =36+1 \\\\ & =37 \end {aligned} 6(6) + 1 = 36 + 1 = 37.
