python - questions repeated 4x, float not callable, error on code -

i dont understand why code doesnt work , have repeated questions me 4 times. , float not callable. have tried doing quite awhile dont seem @ all. there easier way python3? learnt language 2 weeks ago. not whole new world me many of things not familiar with. such indentation

def get_taxi_info():         flag_down = float(input("what's flag-down fare: $"))         within = float(input("what's rate per 400 meters within 9.8km? $"))         beyond = float(input("what's rate per 350 meters beyond 9.8km? $"))         distance = float(input("what's distance traveled (in meters)? "))         peak = input("is ride during peak period? [yes/no]")         mid6 = input("is ride between midnight , 6am? [yes/no]")         location = input("is there location surcharge? [yes/no]")         surloca = float(input("what's amount of location surcharge?"))         return (flag_down, within, beyond, distance, peak == 'yes', mid6 == 'yes', location == 'yes', surloca)      def calculate_taxi_fare():         dist = get_taxi_info()         if dist[3] > 9800:             = (dist[3] - 9800) % 350             if == 0:                 = (extra//350) + 22             else:                 = (extra//350) + 23             return         elif dist[3] <= 9800:             = (dist[3] - 1000) % 400             if == 0:                 = (extra//400)             else:                 = (extra//400) + 1             return      def peakornot():         peak = get_taxi_info()         if peak[4] == true , peak[5] == false:             surcharge = 1.25             return surcharge         elif peak[4] == false , peak[5] == true:             surcharge = 1.50             return surcharge      taxifare = calculate_taxi_fare()     info = get_taxi_info()     peak1 = peakornot()     taxifare = calculate_taxi_fare()     if info[6] == true:         payable = ((info[0] + (info[1] * taxifare()) + (info[2] * taxifare())) * peak1[0]) + info[7]         print ("the total fare $" + str(payable))     elif info[6] == false:         payable = ((info[0] + (info[1] * taxifare()) + (info[2] * taxifare())) * peak1[0]) + info[7]         print ("the total fare $" + str(payable)) 

the function calculate_taxi_fare returns float, on line taxifare float

taxifare = calculate_taxi_fare() 

therefore cannot taxifare() because looks function call, can use example

info[1] * taxifare
