Question

#Computes and outputs travel time
#For a given speed and distance
#Written by Emele Lasaqa 10/10/19

location = input("Enter your location in longitude and latitude: ")
location= int(location)
distance = input("Enter your distance in miles: ")
distance = float(distance)

time = distance/speed

print("At", location, "location latitude location longitude, it will take")
print(time, "hours to travel", distance, "miles.")

input("\n\nPress the Enter ket to exit"

我正在构建一个代码，计算从一个位置到另一个位置的出租车费，所需的距离。但是我一直收到这个错误！有人可以帮我吗？

**This is the OUTPUT**

Enter your location in longitude and latitude: 18.1489° S, 178.4474° E

您的位置是一个字符串，因此无法将其转换为int。您似乎还是不使用它。您也不提供速度。如果是这样，那就更有意义了：

speed = input("Enter your speed: ")
speed = int(speed)
distance = input("Enter your distance in miles: ")
distance = float(distance)

time = distance / speed # works in python 3, if not cast as float
print(f"At {speed} it will take")
print(f"{time} hours to travel {distance} miles.")

您的脚本中有一些错误：

未定义的变量
尝试将字符串解析为整数（建议用户输入纬度，然后输入经度，然后将其转换为浮点数）
print函数仅接受一个参数，python 3中的首选方法是格式化字符串。
