Is there anything in python that can replicate the functionality of freopen() in C or C++? To be precise, I want to replicate the functionality of:
freopen("input.txt","r",stdin);
and
freopen("output.txt","w",stdout);
And then use the same (standard) functions for console I/O for file I/O. Any ideas?

The freopen() function opens the new file associated with stream with the given mode, which is a character string specifying the type of access requested for the file. You can also use the freopen() function to redirect the standard stream files stdin , stdout , and stderr to files that you specify.
freopen("input.txt", "r", stdin); and freopen("output.txt", "w", stdout) are C library function calls that reuse stdin and stdout standard input and standard output stream file pointers as file pointers to the files input.txt and output.txt , respectively.
freopen() prototypeThe freopen function first attempts to close the file opened using stream . After the file is closed, it attempts to open the filename specified by the argument filename (if it is not null) in the mode specified by the argument mode . Finally it associates the file with the file stream stream .
Try this:
import sys
sys.stdin = open('input.txt', 'r')
sys.stdout = open('output.txt', 'w')
Text files are self explanatory. You can now run this code on Sublime Text or any other text editor.
