Question

我是Python 3.6新手，在Python IDLE上使用3.6。我为学校编写了一个程序，可以根据速度和时间计算行进距离。我能够使该程序显示很大的距离数值，但是我希望它在数值之后还显示“ miles”，从而显示测量单位。这是我的代码：

def main（）：

#variable for speed
speed = 60

#variables for time
time1 = 5
time2 = 8
time3 = 12

#variables for distance
distance1 = time1 * speed
distance2 = time2 * speed
distance3 = time3 * speed

#display the distance equations
print ("The distance the car will travel in 5 hours is ", distance1 + " miles")
print ("The distance the car will travel in 8 hours is ", distance2 + "miles")
print ("The distance the car will travel in 12 hours is ", distance3 + "miles")

您可以看到我试图在哪里连接第一个字符串，变量和第二个字符串。这破坏了我的代码。任何帮助表示赞赏！

我建议使用Python中实现的最新最酷的格式设置选项，即formatted string literals：

print(f"The distance the car will travel in 5 hours is {distance1} miles")

但是您也可以执行以下任何操作：

print("The distance the car will travel in 5 hours is {} miles".format(distance1))
print("The distance the car will travel in 5 hours is %s miles" % distance1)
print("The distance the car will travel in 5 hours is", distance1, "miles")
print("The distance the car will travel in 5 hours is" + str(distance1) + " miles")

如何添加字符串，然后添加变量，然后再添加字符串？
