Solve any algebraic equation for the variable x with Mathos AI's Solve for X Calculator. Get instant, step-by-step solutions for linear, quadratic, and polynomial equations. In your example, the second x is the variable used by the for loop, and the first x is simply an expression, which happens in your case to be just x. The expression can be whatever you like, and does not need to be in terms of x. The solve for x calculator allows you to enter a problem and then solve the equation to see the result with respect to the value of x. for x,y in my_list: print(x) print(y) In this case, the for loop is still looping over each of the 4 items in my_list, but it is also doing a tuple unpacking, so the variable x gets the value of the first item in the tuple (the letter) and the variable y gets the value of the second item in the tuple (the number).
