Question

我大便了，我无法排队，我被div汤淹死了。我在这里想念什么？

日期和时间元素未对齐，但我认为这是一个较大的结构问题的一部分。此外，最终版本的单选按钮沿其各自容器的顶部对齐，我尝试使用align-self，但这似乎不起作用。

有什么想法或建议吗？

我当前所在的位置：

结果应该是：

    <div class="row row-content align-items-center">
      <div class="col-12 offset-md-2 col-md-8">
        <div class="card">
          <h3 class="card-header bg-warning text-white">Reserve a Table</h3>
          <div class="card-body">
            <!-- Number of Guests -->
              <label for="numberOfGuests" class="col-md-2 col-form-label"><strong>Number of Guests</strong></label>
              <div class="form-check form-check-inline">
                <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
                <label class="form-check-label" for="inlineRadio1">1</label>
              </div>
              <div class="form-check form-check-inline">

      </div>
    </div>

Answer 1

这应该有效：

def solve_expression(expr, var="x"):
    expr = expr.replace(var, "1j")
    left, right = map(eval, expr.split("="))

    return (right.real-left.real)/(left.imag-right.imag)

print(solve_expression("2*x - 5 = 8"))
print(solve_expression("4*x + 3 = 3*x - 10"))
print(solve_expression("11*x = 2 - (1/5)*x"))
print(solve_expression("4*(x + 2) = 5*(x + 9)"))

Bootstrap-对齐方式已关闭，不确定如何修复
