How to redirect 'print' output to a file using python?

Question

I want to redirect the print to a .txt file using python. I have a \'for\' loop, which will \'print\' the output for each of my .bam file while I want to redirect ALL these

Answer 1

Something to extend print function for loops

x = 0
while x <=5:
    x = x + 1
    with open('outputEis.txt', 'a') as f:
        print(x, file=f)
    f.close()
