freopen in python

Question

Is there anything in python that can replicate the functionality of freopen() in C or C++? what should i do if I want to replicate the functionality of:

freopen("input.txt","r",stdin);
 

and

freopen("output.txt","w",stdout);
 

And also use the same (standard) functions for console I/O for file I/O. how can i do it?

Answer 1

sys.stdout is simply file object, so, you can reopen it to another destination

out = sys.stdout
sys.stdout = open('output.txt', 'w')
// do some work
sys.stdout = out
 

out is only for recovering sys.stdout destination to default after work
