You're probably using Python 2 for the listed script and Python 3 when
you try in the console.

Hello,
Sometimes I find code with strange print function usage. String is passed
without brackets.
#!/usr/bin/python
list = ['physics', 'chemistry', 1997, 2000];
print "Value available at index 2 : "
print list[2]
list[2] = 2001;
print "New value available at index 2 : "
print list[2]

In that case I would skip using print entirely, and use something like this:
import sys
for i in xrange(100):
sys.stdout.write(str(i)

Since you are new, you should also be aware of:

Hi,
I don't want to print the space between 'a' and 'b'. Could somebody

Consider this short script:

st = time()
print 'Start: %f, ' % st,
sleep(10)
sp = time()
print 'Stop: %f, Duration: %f' % (sp, (st - sp))

On my environment (Linux, py24), when run, Python first waits 10s, and
then produces the entire output. How, can I make i

Method one: accumulate your numbers into a single string, then print it in
one go.

You may want to use the write command with stdout:
sys.stdout.write("%s
I want to print 3 numbers without blank.

1
2

Sure I will. Next week, when we come to list operations.

In view of Duncan's response, which invalidates the premises
of my proposal, I announce the end of its short life. I will
add Duncan's solution to my bag of tricks - thank you!

your proposed solution of:

Thank you for your input. The latter form is fine with me personally,
but you just can't explain it to complete novices. My prop
