Switch on Enum in Java [duplicate]
...'m guessing you intended to say you can’t, but you can. chars have a set range of values, so it's easy to compare. Strings can be anything.
A switch statement is usually implemented as a jump table (branch table) in the underlying compilation, which is only possible with a finite set of values. C...
Most common C# bitwise operations on enums

f = open('out.txt', 'w')
sys.stdout = f
for i in range(2):
print 'i = ', i
sys.stdout = orig_stdout
f.close()
Redirecting externally from the shell itself is another good option:
./script.py > out.txt
