Answer:
#Prompt the user to enter the miles.
Miles = float(input('Enter the miles to convert into kilometer: '))
#Check the miles.
if Miles >= 0 :
#Convert the miles to kilometers.
Miles_To_km = Miles*1.6
#Display the result.
print (Miles, "miles equivalent to", Miles_To_km, "kilometer.")
#Prompt the user to enter the gallons.
Gallon = float(input('Enter the gallons to convert into liter: '))
#Check the validity of the Gallons entered.
if Gallon >= 0:
#Convert gallons into liters.
Gal_To_Lit = Gallon*3.9
#Display the result.
print (Gallon, "gallons equivalent to", Gal_To_Lit, "liters.")
#Prompt the user to enter the pounds.
Pound = float(input('Enter the pounds to convert into kilograms: '))
#Check the validity of the Pounds entered.
if Pound >= 0:
#Convert pounds into kilograms.
Pounds_To_Kg = Pound*0.45
#Display the result.
print (Pound, "pounds equivalent to", Pounds_To_Kg, "kilograms.")
#Prompt the user to enter the temperature in Fahrenheit.
f = float(input('Enter the temperature in Fahrenheit: '))
#Check the value to be not greater than 1000.
if f < 1000:
#Convert Fahrenheit into celsius.
F_To_C = (f -32)*5/9
#Display the result.
print (f, "Fahrenheit equivalent to", F_To_C, "celsius.")
#Otherwise.
else:
#Display the error message.
print ("Invalid temperature (greater than 1000) !!!")
else:
#Display the error message.
print ("Pounds cannot be negative !!!")
else:
#Display the error message.
print ("Gallons cannot be negative !!!")
else:
#Display the error message.
print ("Miles cannot be negative !!!")
