Exercise 10:
La conversion des unités de température en Python
Écrivez un programme en Python qui convertit la température de Celsius en Fahrenheit et Kelvin, de Fahrenheit en Celsius et Kelvin, et de Kelvin en Celsius et Fahrenheit.
Code:
def F_C(f):
c = (f - 32) * 5 / 9
return c
def F_K(f):
k = F_C(f)
k = C_K(k)
return k
def K_F(k):
f = K_C(k)
f = C_F(f)
return f
def K_C(k):
c = k - 273.15
return c
def C_F(c):
f = (9 / 5 * c) + 32
return f
def C_K(c):
k = c + 273.15
return k
