Question

我又回到了我用简单的Python项目遇到的更大问题。显然它不仅仅是第16行。其他事情正在发生，我无法弄明白。非常感谢您的智慧。项目代码如下：

#Request user's name
    name = input("Hello! I'm your friendly metric conversion robot. What is your first name? ")

    #Miles to Km Conversion

    #Request miles & format for float
    miles = float(input(name + ", how many miles do you want to convert to kilometers? "))
    #Convert miles to kilometers
    milesToKm = float(miles * 1.6)
    #Display the result
    print(name + ", there are " + str(format(milesToKm,'.2f') + " in " + str(miles) + " miles, ")

    #Fahrenheit to Celsius Conversion

    #Request Fahrenheit temperature
    fahre = input(name + ", what is the temperature in Fahrenheit? "))
    #Convert Fahrenheit to Celsius
    fToC = float((fahre - 32)*(5/9))
    #Display result
    print(name + ", there are "+ str(format(fToC,'.2f')) + " Celsius in " + str(fahre) + " Fahrenheit degrees.")

    #Gallons to Liters Conversion

    #Request gallons
    gallons = float(input(name + ", how many gallons do you want to convert to liters?"))
    #Convert gallons to liters
    galToLiters = float(gallons * 3.9)
    #Display results
    print(name + ", there are " + str(format(galToLiters,'.2f')) + " liters in " + str(gallons) + " gallons.")


    #Pounds to Kilograms Conversion

    #Request pounds
    lbs = float(input(name + ", how many pounds do you want to convert to kilograms?"))
    #Convert pounds to kilograms
    lbsToKilos = float(lbs *0.45)
    #Display results
    print(name + ", there are " + str(format(lbsToKilos,'.2f')) + " in " + str(lbs) + " U.S. pounds.")

    #Inches to Centimeters Conversion

    #Request inches
    inches = float(input(name + ", how many inches do you want to convert to centimeters? "))
    #Convert inches to centimeters
    inchesToCm = float(inches *2.54)
    #Display results
    print(name + ", there are " + str(format(inchesToCm,'.2f')) + " in " + str(inches) + " inches.")

我因语法错误而得到相同的Traceback：

    sys.exit( main(sys.argv) )

  File "<string>", line 16
     fahre = input(name + ", what is the temperature in Fahrenheit? ")
         ^
 SyntaxError: invalid syntax

Answer 1

看起来像一个简单的拼写错误：

fahre = input(name + ", what is the temperature in Fahrenheit? "))

应删除最后)。而你在上面的那一行中错过了一个。

Answer 2

显然主要问题是第16行和第16行的操作数错误。 18.需要一个closing（）和另一个float（）声明。正确的代码如下。感谢大家的帮助！：）

#Request user's name
name = input("Hello! I'm your friendly metric conversion robot. What is your first name? ")

#Miles to Km Conversion

#Request miles & format for float
miles = float(input(name + ", how many miles do you want to convert to kilometers? "))
#Convert miles to kilometers
milesToKm = float(miles * 1.6)
#Display the result
print(name + ", there are " + str(format(milesToKm,'.2f')) + " in " + str(miles) + " miles, ")

#Fahrenheit to Celsius Conversion

#Request Fahrenheit temperature
fahre = float(input(name + ", what is the temperature in Fahrenheit? "))
#Convert Fahrenheit to Celsius
fToC = float((fahre - 32)*(5/9))
#Display result
print(name + ", there are "+ format(fToC,'.2f') + " Celsius in " + str(fahre) + " Fahrenheit degrees.")

#Gallons to Liters Conversion

#Request gallons
gallons = float(input(name + ", how many gallons do you want to convert to liters?"))
#Convert gallons to liters
galToLiters = float(gallons * 3.9)
#Display results
print(name + ", there are " + str(format(galToLiters,'.2f')) + " liters in " + str(gallons) + " gallons.")


#Pounds to Kilograms Conversion

#Request pounds
lbs = float(input(name + ", how many pounds do you want to convert to kilograms?"))
#Convert pounds to kilograms
lbsToKilos = float(lbs *0.45)
#Display results

#Inches to Centimeters Conversion

#Request inches

#Convert inches to centimeters
