Recently I was trying some practice programs in python and I came across this small problem.
when I typed
print ""
in IDLE, the python shell printed a null character.
If I typed
print """"""
in IDLE, the python shell printed a null character.
but the python shell is waits for an input if I type
print """"
Why is this behaviour observed. As far as my knowledge goes, it should print null character for this print """" also.
In python you can have strings enclosed with either 1 or 3 quotes.
print "a"
print """a"""
In your case, the interpreter is waiting for the last triple quote.
I suspect you mean that python printed an empty line -- this is not the same as a null character.
When you print """""", python finds an empty, triple-quoted string.
When you print """", python finds the start of a triple-quoted string, and waits for you to input the rest (ending with """).
A triple-qouted string can include other qoutes, linebreaks, etc.
