What steps will reproduce the problem? 1.If I load a simple "hello, world" program (print "Hello, world!" nothing is printed in the interaction pane. 2.If I have variables, I can tell that the program has executed, but nothing prints. 3. What is the expected output? What do you see instead? "Hello, world!" What version of the product are you using? On what operating system? 4.3 on Windows NT Please provide any additional information below.

I'm seeing this problem too on JES 4.3 on Mac, OS X 10.5.8

Investigated some more, this time on XP I have a simple guessing game program (below) that uses print() and raw_input() I don't see the output from any of the print() calls until the program exits The prompt from the raw_input() appears, however

Thanks,

Andy

import random

def play(): numToGuess = random.randint(1,20) while True: guess = int(raw_input("Guess?")) if guess == numToGuess: print "Yes!!!" break elif guess > numToGuess: print "Too high" else: print "Too low" return

def main(): while True: play() resp = raw_input("Play again?") if resp == "no" or resp == "No": break print "Adios!"

Andy,

There is a printNow function that you might check out.

I'd second this request. I'm thinking of using JES for teaching but the lack of print and input/raw_input statements would mean that sample programs from elsewhere wouldn't work. Not realising this, I tried a baby version of Eliza, and when pasted into JES and run, it appeared to just hang. In reality, it was waiting for input, but it wasn't obvious as nothing was shown to the user.

Given that there's so much tutorial Python info about, and beginners are likely to try and run code they find elsewhere, the inability to run standard python is likely to be confusing.

Any hope of making the standard I/O calls work in the console window?

Thanks - Gino

I've just discovered (using Jes 4.3 on Windows 7), that the print statement does work when it's inside a function, but not if it's at the top level (i.e. so it's executed when a program is Loaded):

def fn(): x = input ("how many times: ") print "this works " * x

print "this doesn't"

Calling fn() from the console displays the input prompt and then the output from the print but the print outside doesn't display anything.

I'm using JES 4.3 on OS X 10.9.5. I find that print doesn't work in a function or outside of one. (And yes, printNow does work.)

Interesting! I've not heard of this bug before. I just tested in OS X 10.10.2, and print is working for me. Could you send some source code that fails?

Here some code that fails:

def print_something(): print "More text"

print "Some text" print_something()

To be clear, this is a problem in the Program Area, but not in the Command Area.

Is this actually

def print_something(): print "More text"

print "Some text" print_something()

Otherwise, Python will complain about the function print_something() doesn't have a body.

Yes, that fails for me in JES 4.3, too. But it works fine in JES 5

Yes, I use only two spaces in my indents.
