Python stdin请求在stdout打印之前到来

Question

I've been trying to learn Python 3.3 recently and run into a problem. Here is the test code I am using:

print('should print before stdin')
x = raw_input('Enter something: ')

And here is what the output looks like:

>>something
should print before stdin
Enter something:

Why are the print statements coming after the stdin?

Answer 1

In Python 3.X, the raw_input("") has been eliminated and so use input() instead. Refer this docs .

print('should print before stdin')
x = input('Enter something: ')

Output

should print before stdin
Enter something: yes
