我使用python 3空闲,它没有突出显示任何东西来告诉我什么语法错误。提到它在第九行,但我看不到它。当运行我的应用程序时,保持得到'SyntaxError:意外的EOF,而解析'当我运行我的应用程序,不知道为什么
下面的代码,它是一个“速度检查”
import time#python module with time related functions
file = open('speeders.txt', 'r')
speeders = file.read()
print (speeders) #prints out list of speeding cars
reg_plate = int(input("Please enter the car's registration plate"))#registration plate
speed_limit = int(input("Please enter your speed limit in mph"))#assigns speed limit
input("Press enter when the car passes the first sensor")#assign values to the end and start time variables
start_time = time.time()
input("Press enter when the car passes the second sensor")
end_time = time.time()
distance = float(input("Enter the distance between the two sensors in metres")) #assigns a value to distance
time_taken = end_time - start_time #works out the time it took the car to travel the length of the road
AverageSpeed = distance/time_taken #works out the average speed of the car
print ("The average speed of the car is", AverageSpeed, "m/s") #prints out the average speed of the car in m/s
AverageSpeedMPH = (AverageSpeed * 2.23694) #converts to mph
print ("That's", AverageSpeedMPH, "in mph") #prints out the speed in mph
if AverageSpeedMPH > speed_limit: #prints out whether car is speeding, adds to txt file
print (reg_plate, "is speeding")
file = open("speeders.txt", "a")
file.write(reg_plate + ",")
file.close()
else:
print (reg_plate, "is not speeding, be on your merry way") #prints out if not speeding
学校项目下面是当应用程序运行
Please enter the car's registration plate5
Please enter your speed limit in mph5
Press enter when the car passes the first sensor
Traceback (most recent call last):
File "C:\Users\Szymon\Google Drive\Computing\Actual CA work\app2.py", line 9, in <module>
input("Press enter when the car passes the first sensor")#lines 3-7 assign values to the end and start time variables

检查你正在使用哪个Python版本,并确保它是你应该在的那个版本。 – user2357112
您是否输入文字,然后按下回车键?或者是从其他地方复制粘贴的“mph5”? – dshapiro
