I want to display a string which is returned by a function in a Python script, without using print:

def myfunc(mystring):
    return "Converting to lowercase :{0}".format(mystring.lower())

result=myfunc("LOWER")
result

But it doesn't give an output. How can I get result to display without print?

Your code does print 'Converting to lowercase :lower' when run in an interactive session (using python or ipython).

It does not, however, print anything if run as part of a script, since there is no implicit printing of expression results.

This is how it's meant to be.

If you want to print something from a script, use print or sys.stdout.write().

An alternative to print:

sys.stdout.write()
