我想在不停止任何功能的情况下中断python中的循环

Question

Before I get to the point, here is my sample code:

x = 0
while x < 50000000:
    x += 1
    print(x)

print("Calculation done")    

As you can see, this code will run for a long period of time. I want to interrupt this 'while loop' without arising any error and get the last print "Calculation done"

Is there any way for it?

Thanks

You could wrap your loop in a try-except :

try:
    x = 0
    while x < 50000000:
        x += 1
        print(x)
except KeyboardInterrupt:
    pass
print("Calculation done")    

Edit: you would stop this with ^C
