How to enter decimal numbers in Python?

Question

Python

Hello. Here is an excerpt from the program code

@app.route('/result', methods=['POST'])
def result():
    var_1 = request.form.get("var_1", type=float)
    var_2 = request.form.get("var_2", type=float)

   operation = request.form.get("operation")
    operation2 = request.form.get("operation2")
    operation3 = request.form.get("operation3")

    if(operation == u'Q (теплота в Дж)' and operation2 == u"q (Электрический заряд в Кл)" and operation3 == u"C (емкость в фарад)"):
        result=(var_1**2) / (2*var_2)

the thing is that I can only enter numbers with a comma, but I also need to enter numbers with a degree, for example 10^-10, but when I enter it, it gives an error, are there data types for such numbers? if int for integers, float for numbers with comma?
