how to remove unnecessary string or words from the user input

Question

If the user gave input like 90C and it should ignore the C

option=input("Please enter the convertion type: \n1.Celsius to Fahrenheit  \n2.Fahrenheit to Celsius\n")
    if option=="1":
        Celsius=float(input("enter temperature in Celsius:"))
        Fahrenheit=(Celsius*(9/5))+32
        print("{0}°C is {1} in Fahrenheit".format(Celsius,Fahrenheit))
    else:
        Fahrenheit=float(input("please enter the temperature in Fahrenheit: "))
        Celsius=(Fahrenheit-32)*(5/9)
        print("{0}F is {1} in Celsius".format(Fahrenheit,Celsius))
