What's wrong with my code to convert farenheight to Celsius?

问题

#Programme to covert Farenheight to Celcius
F=input("Enter Value:")

F=((F-32)/9)*5
       print("The temperature is ",F,"Degrees Celcius")

When i try to run it it says TypeError: unsupported operand type(s) for -: 'str' and 'int'

回答1:

Type cast you input to an int

F=int(input("Enter Value:"))

And force the division to return a float. Add this at the very top

from __future__ import division

回答2:

`F=((float(F)-32)/9)*5`

Or

F=float(input('Enter value'))
[...]`

Input return strings, you have to change them into int or float.

You need to work with floating point numbers:

#Programme to covert Farenheight to Celcius
F = float(input("Enter Value:"))

F = ((F-32.0) / 9.0) * 5.0
print("The temperature is {:.1f} Degrees Celcius".format(F))

Giving you:

Enter Value:33
The temperature is 0.6 Degrees Celcius

The {:.1f} tells it to format F the floating point result as a string to one decimal place.
