How can I get an output of both decimal and whole number?

Question

This is a Fahrenheit to Celsius conversion. I have it set to 2 decimal points as the output but lets say a user enters 50, it will come out as 10.00. How can I get it to come out as 10 without decimal, but allow decimal when it isn't a whole number?

temp = float(input(" Fahrenheit temperature: "))
celsius = float((5/9)*(temp - 32))
print("The temperature in celsius is: {:.2f}°.".format(celsius))

Answer 1

You can try something like this:

temp = float(input(" Fahrenheit temperature: "))
celsius = float((5/9)*(temp - 32))
if (celsius % 1 == 0):
    print("The temperature in celsius is: {}°.".format(celsius))
else:
    print("The temperature in celsius is: {:.2f}°.".format(celsius))

The if condition checks whether or not you have a whole number.

Answer 2

You need to do this separately, because what counts as "close enough" to 50 to display as 50 is application-specific.

if abs(celsius % 1) < 0.001  # Or whatever threshold you want:
    print("The temperature in celsius is: {:d}°.".format(int(celsius//1)))
else:
    print("The temperature in celsius is: {:.2f}°.".format(celsius))

Answer 3

Try This:

def doTheThing(number):
    numString = str(number)
    i = len(numString) -1
    while True:
        if numString[i] == ".":
            numString = numString[:-1] #remove the .
            break
        if numString[i] == "0":
            numString = numString[:-1] #remove the 0
        else:
            break
        i-=1
    print(numString)



x = 10.0
doTheThing(x)

This will print 10, where as regular print will return 10.0

There is probably a better way but this works ;)

您可以在打印时尝试将摄氏度转换为整数：

print("The temperature in celsius is :{:.2f}°.".format(int(celsius)))
