python - 树莓派 : How To Run A Python File From another file

Question

当 python 代码到达特定点时，我有一个 python 代码正在运行(A.py)我必须运行(B.py)，而 A.py 仍在后台运行

A.py

count = 1
while True:
    count++
    if(count%20 == 0)
         //run b
    print "A is running"

B.py

  x = 0
  while x < 10
      print "B is running"

答案必须像

A is running A is running ... 46 times repeat A is running A is running A is running B is running B is running A is running B is running A is running

A和b运行不必同步

    if(count%20 == 0):
         subprocess.Popen("python B.py")
