------
apicheck.py showing "loop running"
please check out this. Why this happening.
Q. How to call a running method and get it's return value ?.
Modify checkapi.py in following way:
#checkapi.py
import time
def add(a,b):
return a + b
def loop():
while True:
time.sleep(10)
print("loop running")
if __name__ == '__main__':
loop()
this will solve your issue. if __name__ == '__main__' says Python to run loop() function only if you execute script itself like python checkapi.py, but if you import it from other module through import checkapi then loop() is not executed and you can use this module without trouble.
import checkapi, theloopfunction starts running, because it saysloop()at the end of that file. Because that function has an infinite loop, nothing else can happen afterward. It's not at all clear what you want to happen instead.if __name__ == "__main__": loop()to guard against this.
