Manually raising two error types with a function that computes sqfeet to sqmeters

[sean1]

How am I able to raise the TypeError when entering a non numerical input? Because of the float(input .... in line 8 a value error is automatically raised. Thanks!

# Area Unit Converter


from configuration import ERROR_NEGATIVE, ERROR_NAN
RATIO_M2F = 10.764
# LIBRARY: function declaration part
# put definitions of functions here
a_value = float(input("Enter area in square feet: "))
def check_one(a_value):
    if float(a_value) < 0:
        raise ValueError(ERROR_NEGATIVE)
    elif type(a_value) != float:
        raise TypeError(ERROR_NAN)


def sqfeet_to_sqmeters(a_value):
    check_one(a_value)
    return a_value / RATIO_M2F ** 2

check_one(a_value)
print(sqfeet_to_sqmeters(a_value))
