重複程序（python）

Question

Heyho

我想在運行任務後重復一個程序。在程序開始時，我會問一些問題，而不是代碼跳到任務中。如果任務完成，sholud再次詢問問題。 每個問題都會在串口讀取一些信息。如果我得到十次信息ich將重新啓動程序..但窗口關閉，我必須啓動該文件。

我該怎麼辦？

import serial 
import struct 
import datetime 

print("\n") 
print("This tool reads the internal Bus ") 
print("-----------------------------------------------------------------------")

       sys.exit(0) 

     file.close() 
     ser.close()

首先，你應該使用如果/艾利芙/ ELSE語句，而不是while循環。

while(i==1): 

應該

if(i==1)0: 

這是一個簡單的程序我寫的，你可以遵循：

# setup a simple run_Task method (prints number of times through the loop already) 
def run_task(count): 
    print "Ran a certain 'task'", count,"times" 

# count is a variable that will count the number of times we pass through a loop 
count = 0 
# loop through 10 times 
while(count<10): 
    # ask questions 
    q1 = raw_input("What is your name?") 
    q2 = raw_input("What is your favorite color?") 

    # run a 'task' 
    run_task(count)
